Wouldn't you like to see what all those headers and their output, ErrorDocuments look like?

]]> AskApache.com

I was trying to find an official, authoritative list of HTTP Status Codes but I kept finding lists that weren't authoritative or complete. So I searched and found my answer in the Apache HTTP Server source code. Once I had the exact HTTP Status Codes and resulting Error Documents sent by Apache, I researched deeper into HTTP Status Codes by reading as many related RFC's as I could find, and several other software source codes were explored. This is the most authoritative list I know of, if you can do better leave a comment and I'll update it. Another thing to keep in mind, the Status code number itself is what is used by software and hardware to make determinations, the phrase returned by the status code is for the human only and does not have any weight other than informing the user.. So "503 Service Unavailable", "503 Service Temporarily Unavailable", and "503 Get the heck outta here" are all completely valid.

Update March 9, 2009: A lot of sites on the web have updated their HTTP status code lists to include the HTTP Status codes listed on this page, including Wikipedia, IANA, W3C, and others, so rest assured this info is accurate and complete. If you'd like to see how to create custom error pages for all of these errors like mine /show-error-506 , then check out this detailed tutorial I just posted.

57 APACHE HTTP STATUS RESPONSE CODES

Once I compiled the list of Apache recognized HTTP Status Codes, I was dying to see them all in action (i.e. the corresponding ErrorDocument). At first I thought I would have to create a php or perl script emulating each of the 57 HTTP Status Codes, a tedious undertaking I wasn't about to do. Instead I "asked Apache" by searching the Apache HTTP Documentation for ambiguity sending Status Codes and/or triggering ErrorDocuments with an Apache Directive.
While reading up on mod_alias and the Redirect directive I found:

Apache Docs

Syntax: Redirect [status] URL-path URL The status argument can be used to return other HTTP status codes. Other status codes can be returned by giving the numeric status code as the value of status. If the status is between 300 and 399, the URL argument must be present, otherwise it must be omitted.

100 Continue
ErrorDocument Continue | Sample 100 Continue
This means that the server has received the request headers, and that the client should proceed to send the request body (in case of a request which needs to be sent; for example, a POST request). If the request body is large, sending it to a server when a request has already been rejected based upon inappropriate headers is inefficient. To have a server check if the request could be accepted based on the requests headers alone, a client must send Expect: 100-continue as a header in its initial request (see RFC 2616 14.20 Expect header) and check if a 100 Continue status code is received in response before continuing (or receive 417 Expectation Failed and not continue).
101 Switching Protocols
ErrorDocument Switching Protocols | Sample 101 Switching Protocols
This means the requester has asked the server to switch protocols and the server is acknowledging that it will do so.[3]
102 Processing
ErrorDocument Processing | Sample 102 Processing
(WebDAV) - (RFC 2518 )
200 OK
ErrorDocument OK | Sample 200 OK
Standard response for successful HTTP requests. The actual response will depend on the request method used. In a GET request, the response will contain an entity corresponding to the requested resource. In a POST request the response will contain an entity describing or containing the result of the action.
201 Created
ErrorDocument Created | Sample 201 Created
The request has been fulfilled and resulted in a new resource being created.
202 Accepted
ErrorDocument Accepted | Sample 202 Accepted
The request has been accepted for processing, but the processing has not been completed. The request might or might not eventually be acted upon, as it might be disallowed when processing actually takes place.
203 Non-Authoritative Information
ErrorDocument Non-Authoritative Information | Sample 203 Non-Authoritative Information
The server successfully processed the request, but is returning information that may be from another source.
204 No Content
ErrorDocument No Content | Sample 204 No Content
The server successfully processed the request, but is not returning any content.
205 Reset Content
ErrorDocument Reset Content | Sample 205 Reset Content
The server successfully processed the request, but is not returning any content. Unlike a 204 response, this response requires that the requester reset the document view.
206 Partial Content
ErrorDocument Partial Content | Sample 206 Partial Content
The server is delivering only part of the resource due to a range header sent by the client. This is used by tools like wget to enable resuming of interrupted downloads, or split a download into multiple simultaneous streams.
207 Multi-Status
ErrorDocument Multi-Status | Sample 207 Multi-Status
(WebDAV) - The message body that follows is an XML message and can contain a number of separate response codes, depending on how many sub-requests were made.
226 IM Used
ErrorDocument IM Used | Sample 226 IM Used
The server has fulfilled a GET request for the resource, and the response is a representation of the result of one or more instance-manipulations applied to the current instance. The actual current instance might not be available except by combining this response with other previous or future responses, as appropriate for the specific instance-manipulation(s).
300 Multiple Choices
ErrorDocument Multiple Choices | Sample 300 Multiple Choices
Indicates multiple options for the resource that the client may follow. It, for instance, could be used to present different format options for video, list files with different extensions, or word sense disambiguation.
301 Moved Permanently
ErrorDocument Moved Permanently | Sample 301 Moved Permanently
This and all future requests should be directed to the given URI.
302 Found
ErrorDocument Found | Sample 302 Found
This is the most popular redirect code[citation needed], but also an example of industrial practice contradicting the standard. HTTP/1.0 specification (RFC 1945 ) required the client to perform a temporary redirect (the original describing phrase was "Moved Temporarily"), but popular browsers implemented it as a 303 See Other. Therefore, HTTP/1.1 added status codes 303 and 307 to disambiguate between the two behaviours. However, the majority of Web applications and frameworks still use the 302 status code as if it were the 303.
303 See Other
ErrorDocument See Other | Sample 303 See Other
The response to the request can be found under another URI using a GET method. When received in response to a PUT, it should be assumed that the server has received the data and the redirect should be issued with a separate GET message.
304 Not Modified
ErrorDocument Not Modified | Sample 304 Not Modified
Indicates the resource has not been modified since last requested. Typically, the HTTP client provides a header like the If-Modified-Since header to provide a time against which to compare. Utilizing this saves bandwidth and reprocessing on both the server and client, as only the header data must be sent and received in comparison to the entirety of the page being re-processed by the server, then resent using more bandwidth of the server and client.
305 Use Proxy
ErrorDocument Use Proxy | Sample 305 Use Proxy
Many HTTP clients (such as Mozilla[4] and Internet Explorer) do not correctly handle responses with this status code, primarily for security reasons.
306 Switch Proxy
ErrorDocument Switch Proxy | Sample 306 Switch Proxy
No longer used.
307 Temporary Redirect
ErrorDocument Temporary Redirect | Sample 307 Temporary Redirect
In this occasion, the request should be repeated with another URI, but future requests can still use the original URI. In contrast to 303, the request method should not be changed when reissuing the original request. For instance, a POST request must be repeated using another POST request.
400 Bad Request
ErrorDocument Bad Request | Sample 400 Bad Request
The request contains bad syntax or cannot be fulfilled.
401 Unauthorized
ErrorDocument Unauthorized | Sample 401 Unauthorized
Similar to 403 Forbidden, but specifically for use when authentication is possible but has failed or not yet been provided. The response must include a WWW-Authenticate header field containing a challenge applicable to the requested resource. See Basic access authentication and Digest access authentication.
402 Payment Required
ErrorDocument Payment Required | Sample 402 Payment Required
The original intention was that this code might be used as part of some form of digital cash or micropayment scheme, but that has not happened, and this code has never been used.
403 Forbidden
ErrorDocument Forbidden | Sample 403 Forbidden
The request was a legal request, but the server is refusing to respond to it. Unlike a 401 Unauthorized response, authenticating will make no difference.
404 Not Found
ErrorDocument Not Found | Sample 404 Not Found
The requested resource could not be found but may be available again in the future. Subsequent requests by the client are permissible.
405 Method Not Allowed
ErrorDocument Method Not Allowed | Sample 405 Method Not Allowed
A request was made of a resource using a request method not supported by that resource; for example, using GET on a form which requires data to be presented via POST, or using PUT on a read-only resource.
406 Not Acceptable
ErrorDocument Not Acceptable | Sample 406 Not Acceptable
The requested resource is only capable of generating content not acceptable according to the Accept headers sent in the request.
407 Proxy Authentication Required
ErrorDocument Proxy Authentication Required | Sample 407 Proxy Authentication Required
Required
408 Request Timeout
ErrorDocument Request Timeout | Sample 408 Request Timeout
The server timed out waiting for the request.
409 Conflict
ErrorDocument Conflict | Sample 409 Conflict
Indicates that the request could not be processed because of conflict in the request, such as an edit conflict.
410 Gone
ErrorDocument Gone | Sample 410 Gone
Indicates that the resource requested is no longer available and will not be available again. This should be used when a resource has been intentionally removed; however, it is not necessary to return this code and a 404 Not Found can be issued instead. Upon receiving a 410 status code, the client should not request the resource again in the future. Clients such as search engines should remove the resource from their indexes.
411 Length Required
ErrorDocument Length Required | Sample 411 Length Required
The request did not specify the length of its content, which is required by the requested resource.
412 Precondition Failed
ErrorDocument Precondition Failed | Sample 412 Precondition Failed
The server does not meet one of the preconditions that the requester put on the request.
413 Request Entity Too Large
ErrorDocument Request Entity Too Large | Sample 413 Request Entity Too Large
The request is larger than the server is willing or able to process.
414 Request-URI Too Long
ErrorDocument Request-URI Too Long | Sample 414 Request-URI Too Long
The URI provided was too long for the server to process.
415 Unsupported Media Type
ErrorDocument Unsupported Media Type | Sample 415 Unsupported Media Type
The request did not specify any media types that the server or resource supports. For example the client specified that an image resource should be served as image/svg+xml, but the server cannot find a matching version of the image.
416 Requested Range Not Satisfiable
ErrorDocument Requested Range Not Satisfiable | Sample 416 Requested Range Not Satisfiable
The client has asked for a portion of the file, but the server cannot supply that portion (for example, if the client asked for a part of the file that lies beyond the end of the file).
417 Expectation Failed
ErrorDocument Expectation Failed | Sample 417 Expectation Failed
The server cannot meet the requirements of the Expect request-header field.
418 I'm a teapot
ErrorDocument I'm a teapot | Sample 418 I'm a teapot
The HTCPCP server is a teapot. The responding entity MAY be short and stout. Defined by the April Fools specification RFC 2324. See Hyper Text Coffee Pot Control Protocol for more information.
422 Unprocessable Entity
ErrorDocument Unprocessable Entity | Sample 422 Unprocessable Entity
(WebDAV) (RFC 4918 ) - The request was well-formed but was unable to be followed due to semantic errors.
423 Locked
ErrorDocument Locked | Sample 423 Locked
(WebDAV) (RFC 4918 ) - The resource that is being accessed is locked
424 Failed Dependency
ErrorDocument Failed Dependency | Sample 424 Failed Dependency
(WebDAV) (RFC 4918 ) - The request failed due to failure of a previous request (e.g. a PROPPATCH).
425 Unordered Collection
ErrorDocument Unordered Collection | Sample 425 Unordered Collection
Defined in drafts of WebDav Advanced Collections, but not present in "Web Distributed Authoring and Versioning (WebDAV) Ordered Collections Protocol" (RFC 3648).
426 Upgrade Required
ErrorDocument Upgrade Required | Sample 426 Upgrade Required
(RFC 2817 ) - The client should switch to TLS/1.0.
449 Retry With
ErrorDocument Retry With | Sample 449 Retry With
A Microsoft extension. The request should be retried after doing the appropriate action.
500 Internal Server Error
ErrorDocument Internal Server Error | Sample 500 Internal Server Error
A generic error message, given when no more specific message is suitable.
501 Not Implemented
ErrorDocument Not Implemented | Sample 501 Not Implemented
The server either does not recognise the request method, or it lacks the ability to fulfil the request.
502 Bad Gateway
ErrorDocument Bad Gateway | Sample 502 Bad Gateway
The server was acting as a gateway or proxy and received an invalid response from the upstream server.
503 Service Unavailable
ErrorDocument Service Unavailable | Sample 503 Service Unavailable
The server is currently unavailable (because it is overloaded or down for maintenance). Generally, this is a temporary state.
504 Gateway Timeout
ErrorDocument Gateway Timeout | Sample 504 Gateway Timeout
The server was acting as a gateway or proxy and did not receive a timely request from the upstream server.
505 HTTP Version Not Supported
ErrorDocument HTTP Version Not Supported | Sample 505 HTTP Version Not Supported
The server does not support the HTTP protocol version used in the request.
506 Variant Also Negotiates
ErrorDocument Variant Also Negotiates | Sample 506 Variant Also Negotiates
(RFC 2295 ) - Transparent content negotiation for the request, results in a circular reference.
507 Insufficient Storage
ErrorDocument Insufficient Storage | Sample 507 Insufficient Storage
(WebDAV) (RFC 4918 )
509 Bandwidth Limit Exceeded
ErrorDocument Bandwidth Limit Exceeded | Sample 509 Bandwidth Limit Exceeded
(Apache bw/limited extension) - This status code, while used by many servers, is not specified in any RFCs.
510 Not Extended
ErrorDocument Not Extended | Sample 510 Not Extended
(RFC 2774 ) - Further extensions to the request are required for the server to fulfil it.

1xx Info / Informational

HTTP_INFO - Request received, continuing process. Indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line.

2xx Success / OK

HTTP_SUCCESS - The action was successfully received, understood, and accepted. Indicates that the client's request was successfully received, understood, and accepted.

3xx Redirect

HTTP_REDIRECT - The client must take additional action to complete the request. Indicates that further action needs to be taken by the user-agent in order to fulfill the request. The action required may be carried out by the user agent without interaction with the user if and only if the method used in the second request is GET or HEAD. A user agent should not automatically redirect a request more than 5 times, since such redirections usually indicate an infinite loop.

4xx Client Error

HTTP_CLIENT_ERROR - The request contains bad syntax or cannot be fulfilled. Indicates case where client seems to have erred. Except when responding to a HEAD request, the server should include an entity containing an explanation of the error situation, and whether it is a temporary or permanent condition.

5xx Server Error

HTTP_SERVER_ERROR - The server failed to fulfill an apparently valid request. Indicate cases in which the server is aware that it has erred or is incapable of performing the request. Except when responding to a HEAD request, the server should include an entity containing an explanation of the error situation, and whether it is a temporary or permanent condition. User agents should display any included entity to the user. These response codes are applicable to any request method.

Quick Start to triggering ErrorDocuments for each Status Code

Let start with a quick and easy example. Add the following Redirect rules to your htaccess file, then open your browser and goto each url like yoursite.com/e/400. Don't create an /e/ directory or any files.

Redirect 400 /e/400
Redirect 503 /e/503
Redirect 405 /e/405

Apache ErrorDocument Results
error 503

Automate the ErrorDocument Triggering

The htaccess Redirects

When a Status code is encountered, Apache outputs the Header and the ErrorDocument for that error code. So you can view any Header and the default ErrorDocument, by causing that numerical error code, which is caused by the Status Code.

For instance, if you request a file that doesn't exist, a 404 Not Found Header is issued and the corresponding ErrorDocument is served with the 404 Not Found Header.

PHP script that gets and outputs the Headers/Content

Now all I have to do is add 57 Redirect Directives to my htaccess, and then request each of them 1 at a time from my browser to see the result, and use a packet sniffing program like WireShark to see the Headers. Uh, scratch that, that would take way too long!

Instead I hacked up a simple php script using cURL to automate sending GET Requests to each of the 57 Redirect URL-paths. A side benefit of using the php script is that it performs all 57 Requests concurrently and saves each Requests returned headers and content to an output buffer. After all 57 have been queried, the output buffer is flushed to the browser.

WordPress 2.8 Changes

I just learned that my modification to the WordPress core was accepted and will be implemented for version 2.8! This may mean WordPress is the only 100% HTTP/1.1 compliant software on the net! Below is the new list (I thought someone out there could use the php array) and as you can see, unfortunately418 I'm a teapotdidn't make it ;)

RIPE WHOIS

All the status codes are standard HTTP codes ( http://www.iana.org/assignments/http-status-codes ).

Clients should avoid any form of coupling with the the text/plain error message contained in response body since it may change between different releases of the API and is only intended as a starting point for indentifying the real causes of the exception event.

The following table gives a brief description of the mapping between standard Whois V.3 responses and the related REST services status codes. Consider this table as just an example of the error mapping strategy, it may change with future releases.

System Exception Whois Error HTTP Status Code
IllegalArgumentException Bad Request (400)
IllegalStateException Internal Server Error (500)
UnsupportedOperationException Bad Request (400)
ObjectNotFoundException Not Found (404)
IllegalStateException Bad Request (400)
IOException Bad Request (400)
SystemException Internal Server Error (500)
TooManyResultsException Internal Server Error (500)
WhoisServerException No Entries Found (101) Not Found (404)
WhoisServerException Unknown Source (102) Bad Request (400)
WhoisServerException Unknown Object Type (103) Bad Request (400)
WhoisServerException Unknown Attribute in Query (104) Bad Request (400)
WhoisServerException Attribute Is Not Inverse Searchable (105) Bad Request (400)
WhoisServerException No Search Key Specified (106) Bad Request (400)
WhoisServerException Access Denied (201) Forbidden (403)
WhoisServerException Access Control Limit Reached (202) Forbidden (403)
WhoisServerException Address Passing Not Allowed (203) Bad Request (400)
WhoisServerException Maximum Referral Lines Exceeded (204) Internal Server Error (500)
WhoisServerException Connection Has Been Closed(301) Internal Server Error (500)
WhoisServerException Referral Timeout (302) Internal Server Error (500)
WhoisServerException No Referral Host (303) Internal Server Error (500)
WhoisServerException Referral Host Not Responding (304) Internal Server Error (500)

Clients will have to define error messages generic enough to represent the four main error conditions, that are Bad Request, Forbidden, Not Found and Internal Server Error.

For example a possible mapping for client side error messages may be:

HTTP Status Code Error Message
Bad Request (400) The service is unable to understand and process the query.
Forbidden (403) Query limit exceeded.
Not Found (404) No results were found for Your search "Search term"
Internal Server Error (500) The server encountered an unexpected condition which prevented it from fulfilling the request.

I was going through some backups from years ago, and ran:

locate .htaccess | xargs -I'{}' cat '{}' >> master-htaccesser.txt

My site is named after reading source code because that is what helps me the most when I'm trying to learn something unusually difficult. Just like functions and aliases, it is very helpful to have cheatsheets for common commands.. not much is better than real-world examples. Unfortunately because this was compiled from hundreds of htaccess files on multiple hosts and platforms, and due to the concatenation, it's not organized.

Normally I would not publish something like this, who knows how much unreleased tricks I forgot about.. but in order to say thanks to all those working for open-source, the FSF, and to all those who don't steal content, and to all the incredible authors who shared with me (I twitter most of what I find, and follow my favs), here ya go..

ATTN: Please let me know if this is total junk or not, this is around 1/500th of my master-htaccesser.txt file.. and I'd be happy to post more if it helps..

### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#
#
# TZ: Your address, where problems with the server should be
# e-mailed.  This address appears on some server-generated pages, such
# as error documents.  e.g. admin@your-domain.com
#
SetEnv TZ America/Indianapolis
 
#
# ServerAdmin: Your address, where problems with the server should be
# e-mailed.  This address appears on some server-generated pages, such
# as error documents.  e.g. admin@your-domain.com
#
SetEnv SERVER_ADMIN webmaster@askapache.com
 
#
# Optionally add a line containing the server version and virtual host
# name to server-generated pages (internal error documents, FTP directory
# listings, mod_status and mod_info output etc., but not CGI generated
# documents or custom error documents).
# Set to "EMail" to also include a mailto: link to the ServerAdmin.
# Set to one of:  On | Off | EMail
#
ServerSignature Off
 
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
#   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# The Options directive is both complicated and important.  Please see
# http://httpd.apache.org/docs/2.0/mod/core.html#options
# for more information.
#
Options -Indexes -Includes -ExecCGI -MultiViews
 
#
# DirectoryIndex: sets the file that Apache will serve if a directory
# is requested.
#
DirectoryIndex index.php
 
#
# Action lets you define media types that will execute a script whenever
# a matching file is called. This eliminates the need for repeated URL
# pathnames for oft-used CGI file processors.
# Format: Action media/type /cgi-script/location
# Format: Action handler-name /cgi-script/location
#
Action php5-cgi /bin/php.cgi
 
#
# AddHandler allows you to map certain file extensions to "handlers":
# actions unrelated to filetype. These can be either built into the server
# or added with the Action directive (see below)
#
# To use CGI scripts outside of ScriptAliased directories:
# (You will also need to add "ExecCGI" to the "Options" directive.)
#
AddHandler php5-cgi .php .inc
 
#
# Commonly used filename extensions to character sets. You probably
# want to avoid clashes with the language extensions, unless you
# are good at carefully testing your setup after each change.
# See http://www.iana.org/assignments/character-sets for the
# official list of charset names and their respective RFCs.
#
AddDefaultCharset UTF-8
 
#
# AddType allows you to add to or override the MIME configuration
# file mime.types for specific file types.
#

AddType video/x-flv .flv
 
#
# AddEncoding allows you to have certain browsers uncompress
# information on the fly. Note: Not all browsers support this.
# Despite the name similarity, the following Add* directives have nothing
# to do with the FancyIndexing customization directives above.
#
AddEncoding x-compress .Z
AddEncoding x-gzip .gz .tgz
 
#
# DefaultType: the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value.  If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are
# text.

# Pass: Allows request to continue, further filters could still halt request.
# Allow: Allows matching requests through, will not be tested against other filters.
# Deny: Stops the request outright, returns a HTTP 500 error code by default.
# Status: Used to specify an alternate HTTP error code.
# Redirect: Matching requests are redirected to the provided URL.
# Exec: Allows execution of a local system binary or script.
# Log: Logs request only.
# Nolog: Does not log request.
# Chain: Allows you to create list of filters for more granulated security. All filters must be cleared before action is taken with the final filter.

Passing Parameters to CGI through HTTP Headers

This deserves a note.. this trick lets you bypass so many hosting environment restrictions it's not even funny... like you can run bash as your webserver instead of apache! (kinda...)

RewriteCond %{REQUEST_URI} ^/cgi-bin/(hash|java)\.cgi$ [NC]

RewriteRule .* - [E=HTTP_JS:%{HTTP:P3P},E=HTTP_US:%2,E=HTTP_PA:%3]

Redirect to FeedBurner

Yes.. I was the first to do this (parse the real rewrites internally in wordpress for no bypassing possibilities)...

### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#
#
# TZ: Your address, where problems with the server should be
# e-mailed.  This address appears on some server-generated pages, such
# as error documents.  e.g. admin@your-domain.com
#
SetEnv TZ America/Indianapolis
 
#
# ServerAdmin: Your address, where problems with the server should be
# e-mailed.  This address appears on some server-generated pages, such
# as error documents.  e.g. admin@your-domain.com
#
SetEnv SERVER_ADMIN webmaster@askapache.com
 
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
#   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# The Options directive is both complicated and important.  Please see
# http://httpd.apache.org/docs/2.0/mod/core.html#options
# for more information.
#
Options  +FollowSymLinks -ExecCGI -Indexes -Includes -MultiViews
 
#
# DirectoryIndex: sets the file that Apache will serve if a directory
# is requested.
#
DirectoryIndex index.html index.php /index.php
 
#
# The following lines prevent .htaccess and .htpasswd files from being
# viewed by Web clients.
#
<filesMatch "^\.ht">
    Order allow,deny
    Deny from all
  Satisfy All
</filesMatch>
 
#
# DefaultType: the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value.  If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are
# text.
#
DefaultType text/html
 
#
# Optionally add a line containing the server version and virtual host
# name to server-generated pages (internal error documents, FTP directory
# listings, mod_status and mod_info output etc., but not CGI generated
# documents or custom error documents).
# Set to "EMail" to also include a mailto: link to the ServerAdmin.
# Set to one of:  On | Off | EMail
#
ServerSignature Off

Note: The history feature works by remembering the last commands that you typed.. Access them by pressing the up or down arrows on your keyboard.

This is not an interactive session, so you cannot cd to a directory and then do stuff in that directory.. You may however be able to do stuff like /bin/bash -c "cd ../../;mv this there;ls -la;" or you could try exporting your current dir or something..

Writing shell scripts and serving them on your web server works by renaming the file.sh to file.cgi and chmodding it to 750 or +x. Also make sure you try dos2unix -dv file.cgi If you can't get it to work..

Example shell script as cgi

#!/bin/sh
export MYBNAME=`date +%mx%dx%y-%Hx%M.tgz`
tar -czf ${HOME}/backups/${MYBNAME} ${HOME}/site1/
exit 0;

Locking Down Access to your shell.php

Thanks to the comment by Andrew Ramsden, Here are a couple ways to secure your shell.php file so that only you can run this script.

Secure your remote shell by adding this to your shell.php

Add this line to the very top of your shell.php file to make sure that only you can access this script. Everyone else sees a blank screen.

if ($_SERVER['REMOTE_ADDR'] !== '1.1.1.1') die();

Secure your remote shell with htaccess

This only allows access from IP 1.1.1.1 and redirects everyone else. See Using the Allow Directive in Apache htaccess for more info.

Order deny,allow
Deny from all
Allow from 1.1.1.1
ErrorDocument 403 http://www.askapache.com

Secure your remote shell with mod_rewrite and htaccess

Based on the code from htaccess article This only allows access from user with IP of 1.1.1.1 and redirects everyone else.

RewriteEngine On
RewriteBase /
RewriteCond %{REMOTE_HOST} !^1\.1\.1\.1
RewriteRule .* http://www.askapache.com [R=302,L]

SSI, Server Side Includes, can be very useful to webmasters and visitors alike. They are easily set up in an .htaccess file and require little to no maintaining.. the term "Set it and Forget it" applies here. Before we look at how to implement SSI, and dig into the Apache module that makes them possible, lets look at few uses for SSI so you can quickly determine if you would like to read further.

Improved Directory Listings and SEO

htaccess directory indexingOne way that I use SSI is for improved Directory Listing. Anyone here like SEO? Check out my WordPress uploads directory to get an idea. Basically I can customize the header and footer of each directory.. Pretty sweet, thanks Apache!

In your /uploads/.htaccess

# turn on auto-indexing and turn off SSI's ability to exec
Options None
Options SymLinksIfOwnerMatch Indexes IncludesNOEXEC
 
# we need to make sure files are displayed when requested, not executed or parsed
AddType text/plain .ini .sh .bsh .bash .csh .var .asc .md5 .sha .sha1 .cgi .pl .php .inc .asp .exe .bin
DefaultType text/plain
 
# turn on auto-indexing, with askapache-optimized options
IndexOptions FancyIndexing SuppressColumnSorting SuppressHTMLPreamble IconHeight=22 IconWidth=20
IndexOptions IgnoreClient NameWidth=40 DescriptionWidth=* XHTML FoldersFirst
 
# don't show these files and folders
IndexIgnore .htaccess .ht* *_notes *.log feed inc HEADER.html FOOTER.html feed*.gif
 
# the SSI files used for the header and footer

# used to determine the time and for SSI output
SetEnv TZ America/Indianapolis
SetEnv SERVER_ADMIN webmaster@askapache.com

In your /ssi/.htaccess

# makes files ending in .html be filtered through the INCLUDES filter before being sent to client
AddOutputFilter Includes html

Enhanced Error Pages

ErrorDocument from .htaccessIf you are using WordPress, I'm sure you are using my AskApache Google 404 Plugin, but whatever your error pages may be, using SSI you can make them better. My 404 Error Page is handled by WordPress and PHP, but all of my other error pages (codes 4xx to 5xx) are handled using SSI. You can check out any of them: /show-error-400, /show-error-403, /show-error-503, etc..

Notice the email note which has the subject prefilled? Thats one of the main uses for SSI, you can add forms to your errordocuments and get notified of problems which mean you can fix them.

Add this to your /.htaccess for each ErrorDocument you make.

ErrorDocument 503 /errordocs/503.html

Dealing with Spam and Website Attacks

htaccess SSI to scare spammers and crackersSay you are using some nice .htaccess rewrite rules to block offending bots, web scrapers, and other nefarious net characters. Instead of just sending a 403 Denied, you could send them to be handled by an SSI document that could do any number of things.. From adding the offending bot's IP address to the .htaccess Deny List (blacklisting), emailing you with an alert, emailing the IP Block Owner, executing a denial-of-service response ala guardian (script will return an artificially high Content-Length, and will then spoon-feed content bytes back to the client at a rate of one byte per second, for single-threaded or fixed-threadpool clients, this will hang all of their requests and render the attack inoperable), or just output a frightening looking message which usually does the trick if the bot is humanoid.

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /.*\?\=?(http|ftp|ssl|https):/.*\ HTTP/ [NC,OR]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /.*\?\?.*\ HTTP/ [NC,OR]

Server Side Includes Detailed Info

Ok now that we have the real-world usage out of the way, lets dig in a bit to the actual module mod_include, which if you want you can view the source code here.

Enabling Server-Side Includes

Server Side Includes are implemented by the INCLUDES filter. For backwards compatibility, the server-parsed handler also activates the INCLUDES filter. As well, Apache will activate the INCLUDES filter for any document with mime type text/x-server-parsed-html or text/x-server-parsed-html3 (and the resulting output will have the mime type text/html). If documents containing server-side include directives are given the extension .shtml, the following directives will make Apache parse them and assign the resulting document the mime type of text/html:

AddType text/html .shtml
AddOutputFilter INCLUDES .shtml

The following directive must be given for the directories containing the shtml files (typically in a section, but this directive is also valid in .htaccess files if AllowOverride Options is set):

Options +Includes

Server-Side Include Directives

These are the Directives allowed in .htaccess files that are handled by mod_include. Note that other modules may add additional directives, for instance the exec SSI Directive is supplied by mod_cgi. This is how mod_cgi registers with mod_include to provide processing of the exec directive. This is the code required to handle the "exec" SSI directive.

cgi_pfn_reg_with_ssi = APR_RETRIEVE_OPTIONAL_FN(ap_register_include_handler);
cgi_pfn_reg_with_ssi("exec", handle_exec);
static const char * const aszPre[] = { "mod_include.c", NULL };
config
Controls various aspects of the parsing.

<!--#config [timefmt="..."] [sizefmt="..."] [errmsg="..."] -->
<!--#config [echomsg="..."] -->
<!--#config errmsg="[It appears that you don't know how to use SSI]" -->
echomsg
(since 2.1) The value is a message that is sent back to the client if the <a href="#element.echo">echo</a> element attempts to echo an undefined variable. This overrides any <a href="#ssiundefinedecho">SSIUndefinedEcho</a> directives.
errmsg
The value is a message that is sent back to the client if an error occurs while parsing the document. This overrides any <a href="#ssierrormsg">SSIErrorMsg</a> directives.
sizefmt
The value sets the format to be used which displaying the size of a file. Valid values are bytes for a count in bytes, or abbrev for a count in Kb or Mb as appropriate, for example a size of 1024 bytes will be printed as "1K".
timefmt
The value is a string to be used by the strftime(3) library routine when printing dates.
echo
Prints one of the include variables. If the variable is unset, the result is determined by the SSIUndefinedEcho directive.

<!--#echo [encoding="none|url|entity"] var="..." [encoding="none|url|entity"] var="..." ... -->
var
The value is the name of the variable to print.
encoding

Specifies how Apache should encode special characters contained in the variable before outputting them. If set to none, no encoding will be done. If set to url, then URL encoding (also known as %-encoding; this is appropriate for use within URLs in links, etc.) will be performed. The default is set to entity, resulting in entity encoding.

exec
Execute external programs

<!--#exec cgi="/cgi-bin/s.cgi" -->
<!--#exec cmd="ls" -->
<!--#include virtual="/cgi-bin/s.cgi?argument=value" -->
<!--#exec cmd="perl /cgi-bin/s.pl args" -->
include
Include a file

<!--#include virtual|file="..." [virtual|file="..."] ... -->
printenv
Print all available variables

<!--#printenv -->
set
Set a value of a variable.

<!--#set var="..." value="..." ... -->
<!--#set var="modified" value="$LAST_MODIFIED" -->
<!--#set var="name" value="AskApache" -->
<!--#set var="date" value="${DATE_LOCAL}_${DATE_GMT}" -->
flastmod
Prints the last modification date of the specified file, subject to the timefmt format specification.

<!--#flastmod virtual|file="..." [virtual|file="..."] ... -->
fsize
Prints the size of the specified file, subject to the sizefmt format specification.

<!--#fsize virtual|file="..." [virtual|file="..."] ... -->
if
The if element works like an if statement in a programming language. The test condition is evaluated and if the result is true, then the text until the next elif, else or endif element is included in the output stream.

<!--#if expr="..." -->
<!--#if expr="${REMOTE_USER} && ${HTTP_USER_AGENT}" -->
<!--#if expr="test_condition" -->
<!--#elif expr="test_condition" -->
<!--#else -->
<!--#endif -->
elif
Used to put text into the output stream if the original test_condition was false. 

<!--#elif expr="..." -->
else
Used to put text into the output stream if the original test_condition was false.

<!--#else -->
endif
Ends the if element and is required.

<!--#endif -->

I discovered these tips and tricks mostly while working as a network security penetration specialist hired to find security holes in web hosting environments. Shared hosting is the most common and cheapest form of web-hosting where multiple customers are placed on a single machine and "share" the resources (CPU/RAM/SPACE). The machines are configured to basically ONLY do HTTP and FTP. No shells or any interactive logins, no ssh, just FTP access. That is when I started examining htaccess files in great detail and learned about the incredible untapped power of htaccess. For 99% of the worlds best Apache admins, they don't use .htaccess much, if AT ALL. It's much easier, safer, and faster to configure Apache using the httpd.conf file instead. However, this file is almost never readable on shared-hosts, and I've never seen it writable. So the only avenue left for those on shared-hosting was and is the .htaccess file, and holy freaking fiber-optics.. it's almost as powerful as httpd.conf itself!

Most all .htaccess code works in the httpd.conf file, but not all httpd.conf code works in .htaccess files, around 50%. So all the best Apache admins and programmers never used .htaccess files. There was no incentive for those with access to httpd.conf to use htaccess, and the gap grew. It's common to see "computer gurus" on forums and mailing lists rail against all uses and users of .htaccess files, smugly announcing the well known problems with .htaccess files compared with httpd.conf - I wonder if these "gurus" know the history of the htaccess file, like it's use in the earliest versions of the HTTP Server- NCSA's HTTPd, which BTW, became known as Apache HTTP. So you could easily say that htaccess files predates Apache itself.

Once I discovered what .htaccess files could do towards helping me enumerate and exploit security vulnerabilities even on big shared-hosts I focused all my research into .htaccess files, meaning I was reading the venerable Apache HTTP Source code 24/7! I compiled every released version of the Apache Web Server, ever, even NCSA's, and focused on enumerating the most powerful htaccess directives. Good times!

.htaccess is a very ancient configuration file that controls the Web Server running your website, and is one of the most powerful configuration files you will ever come across. Htaccess has the ability to control access of the WWW's HyperText Transfer Protocol (HTTP) using Password Protection, 301 Redirects, rewrites, and much much more. This is because this configuration file was coded in the earliest days of the web (HTTP), for one of the first Web Servers ever! Eventually these Web Servers (configured with htaccess) became known as the World Wide Web, and eventually grew into the Internet we use today.

.htaccess file tutorialThis is not an introduction to .htaccess… This is the evolution of the best of the best .htaccess on the planet. Its changed over the years with more and better .htaccess tricks using real .htaccess example code. I add my favorite htaccess-related links and sites, results from my htaccess research, and frequently update this article.

You've come to the right place if you are looking to acquire mad skills for using .htaccess files.

Originally (2003) this guide was known in certain hacker circles and hidden corners of the net as an ultimate .htaccess due to the powerful htaccess tricks and tips to bypass security on a webhost, and also because many of the tricks and examples were pretty impressive back then in that group.

AskApache Htaccess Journey

Skip this - still under edit

I discovered these tips and tricks mostly while working as a network security penetration specialist hired to find security holes in web hosting environments. Shared hosting is the most common and cheapest form of web-hosting where multiple customers are placed on a single machine and "share" the resources (CPU/RAM/SPACE). The machines are configured to basically ONLY do HTTP and FTP. No shells or any interactive logins, no ssh, just FTP access. That is when I started examining htaccess files in great detail and learned about the incredible untapped power of htaccess. For 99% of the worlds best Apache admins, they don't use .htaccess much, if AT ALL. It's much easier, safer, and faster to configure Apache using the httpd.conf file instead. However, this file is almost never readable on shared-hosts, and I've never seen it writable. So the only avenue left for those on shared-hosting was and is the .htaccess file, and holy freaking fiber-optics.. it's almost as powerful as httpd.conf itself!

Most all .htaccess code works in the httpd.conf file, but not all httpd.conf code works in .htaccess files, around 50%. So all the best Apache admins and programmers never used .htaccess files. There was no incentive for those with access to httpd.conf to use htaccess, and the gap grew. It's common to see "computer gurus" on forums and mailing lists rail against all uses and users of .htaccess files, smugly announcing the well known problems with .htaccess files compared with httpd.conf - I wonder if these "gurus" know the history of the htaccess file, like it's use in the earliest versions of the HTTP Server- NCSA's HTTPd, which BTW, became known as Apache HTTP. So you could easily say that htaccess files predates Apache itself.

Once I discovered what .htaccess files could do towards helping me enumerate and exploit security vulnerabilities even on big shared-hosts I focused all my research into .htaccess files, meaning I was reading the venerable Apache HTTP Source code 24/7! I compiled every released version of the Apache Web Server, ever, even NCSA's, and focused on enumerating the most powerful htaccess directives. Good times! Because my focus was on protocol/file/network vulnerabilites instead of web dev I built up a nice toolbox of htaccess tricks to do unusual things. When I switched over to webdev in 2005 I started using htaccess for websites, not research. I documented most of my favorites and rewrote the htaccess guide for webdevelopers. After some great encouragement on various forums and nets I decided to start a blog to share my work with everyone, AskApache.com was registered, I published my guide, and it was quickly plagiarized and scraped all over the net.

Htaccess - Evolved

The Hyper Text Transfer Protocol (HTTP) was initiated at the CERN in Geneve (Switzerland), where it emerged (together with the HTML presentation language) from the need to exchange scientific information on a computer network in a simple manner. The first public HTTP implementation only allowed for plain text information, and almost instantaneously became a replacement of the GOPHER service. One of the first text-based browsers was LYNX which still exists today; a graphical HTTP client appeared very quickly with the name NCSA Mosaic. Mosaic was a popular browser back in 1994. Soon the need for a more rich multimedia experience was born, and the markup language provided support for a growing multitude of media types.

Htaccess file know-how will do several things for you:

  • Make your website noticeably faster.
  • Allow you to debug your server with ease.
  • Make your life easier and more rewarding.
  • Allow you to work faster and more productively.

What Is .htaccess

Specifically, .htaccess is the default file name of a special configuration file that provides a number of directives (commands) for controlling and configuring the Apache Web Server, and also to control and configure modules that can be built into the Apache installation, or included at run-time like mod_rewrite (for htaccess rewrite), mod_alias (for htaccess redirects), and mod_ssl (for controlling SSL connections).

Htaccess allows for decentralized management of Web Server configurations which makes life very easy for web hosting companies and especially their savvy consumers. They set up and run "server farms" where many hundreds and thousands of web hosting customers are all put on the same Apache Server. This type of hosting is called "virtual hosting" and without .htaccess files would mean that every customer must use the same exact settings as everyone else on their segment. So that is why any half-decent web host allows/enables (DreamHost, Powweb, MediaTemple, GoDaddy) .htaccess files, though few people are aware of it. Let's just say that if I was a customer on your server-farm, and .htaccess files were enabled, my websites would be a LOT faster than yours, as these configuration files allow you to fully take advantage of and utilize the resources allotted to you by your host. If even 1/10 of the sites on a server-farm took advantage of what they are paying for, the providers would go out of business.

One of the design goals for this server was to maintain external compatibility with the NCSA 1.3 server --- that is, to read the same configuration files, to process all the directives therein correctly, and in general to be a drop-in replacement for NCSA. On the other hand, another design goal was to move as much of the server's functionality into modules which have as little as possible to do with the monolithic server core. The only way to reconcile these goals is to move the handling of most commands from the central server into the modules.

However, just giving the modules command tables is not enough to divorce them completely from the server core. The server has to remember the commands in order to act on them later. That involves maintaining data which is private to the modules, and which can be either per-server, or per-directory. Most things are per-directory, including in particular access control and authorization information, but also information on how to determine file types from suffixes, which can be modified by AddType and DefaultType directives, and so forth. In general, the governing philosophy is that anything which can be made configurable by directory should be; per-server information is generally used in the standard set of modules for information like Aliases and Redirects which come into play before the request is tied to a particular place in the underlying file system.

Another requirement for emulating the NCSA server is being able to handle the per-directory configuration files, generally called .htaccess files, though even in the NCSA server they can contain directives which have nothing at all to do with access control. Accordingly, after URI -> filename translation, but before performing any other phase, the server walks down the directory hierarchy of the underlying filesystem, following the translated pathname, to read any .htaccess files which might be present. The information which is read in then has to be merged with the applicable information from the server's own config files (either from the <directory> sections in access.conf, or from defaults in srm.conf, which actually behaves for most purposes almost exactly like <directory />).

Finally, after having served a request which involved reading .htaccess files, we need to discard the storage allocated for handling them. That is solved the same way it is solved wherever else similar problems come up, by tying those structures to the per-transaction resource pool.

Creating Htaccess Files

What an Htaccess File Looks Like in Windows ExplorerHtaccess files use the default filename ".htaccess" but any unix-style file name can be specified from the main server config using the AccessFileName directive. The file isn't .htaccess.txt, its literally just named .htaccess.

View .htaccess filesIn a Windows Environment like the one I use for work, you can change how Windows opens and views .htaccess files by modifying the Folder Options in explorer. As you can see, on my computer files ending in .htaccess are recognized as having the HTACCESS extension and are handled/opened by Adobe Dreamweaver CS4.

Htaccess Scope

Unlike the main server configuration files like httpd.conf, Htaccess files are read on every request therefore changes in these files take immediate effect. Apache searches all directories and subdirectories that are htaccess-enabled for an .htaccess file which results in performance loss due to file accesses. I've never noticed a performance loss but OTOH, I know how to use them. If you do have access to your main server configuration file, you should of course use that instead, and lucky for you ALL the .htaccess tricks and examples can be used there as well (just not vice versa).

Htaccess File Syntax

Htaccess files follow the same syntax as the main Apache configuration files, for powerusers here's an apache.vim for VI. The one main difference is the context of the directive, which means whether or not that directive is ALLOWED to be used inside of an .htaccess file. Htaccess files are incredibly powerful, and can also be very dangerous as some directives allowed in the main configuration files would allow users/customers to completely bypass security/bandwidth-limits/resource-limits/file-permissions, etc.. About 1/4 of all Apache directives cannot be used inside an .htaccess file (also known as a per-directory context config). The Apache Developers are well-regarded throughout the world as being among some of the best programmers, ever. To enable a disallowed directive inside a .htaccess file would require modifying the source code and re-compiling the server (which they allow and encourage if you are the owner/admin). Here's a taste of that famous Apache source code that builds the directives allowed in .htaccess file context, the key that tells whether its enabled in .htaccess context is the DIR_CMD_PERMS and then the OR_FILEINFO, which means a directive is enabled dependent on the AllowOverride directive that is only allowed in the main config. First Apache 1.3.0, then Apache 2.2.10

Htaccess Directives

Don't ask why, but I personally downloaded each major/beta release of the Apache HTTPD source code from version 1.3.0 to version 2.2.10 (all 63 Apache versions!), then I configured and compiled each version for a custom HTTPD installation built from source. This allowed me to find every directive allowed in .htaccess files for each particular version, which has never been done before, or since. YES! I think that is so cool..

An .htaccess directive is basically a command that is specific to a module or builtin to the core that performs a specific task or sets a specific setting for how Apache serves your WebSite. Directives placed in Htaccess files apply to the directory they are in, and all sub-directories. Here's the 3 top links (official Apache Docs) you will repeatedly use, bookmark/print/save them.

Litespeed Htaccess support

Unlike other lightweight web servers, Apache compatible per-directory configuration overridden is fully supported by LiteSpeed Web Server. With .htacess you can change configurations for any directory under document root on-the-fly, which in most cases is a mandatory feature in shared hosting environment. It is worth noting that enabling .htaccess support in LiteSpeed Web Server will not degrade server's performance, comparing to Apache's 40% drop in performance.

Main Server Config Examples

Now lets take a look at some htaccess examples to get a feel for the syntax and some general ideas at the capabilities. Some of the best examples for .htaccess files are included with Apache for main server config files, so lets take a quick look at a couple of them on our way down to the actual .htaccess examples further down the page (this site has thousands, take your time). As you can see, the basic syntax is a line starting with # is a comment, everything else are directives followed by the directive argument.

HTTP to HTTPS Redirects with mod_rewriteThis is freaking sweet if you use SSL I promise you! Basically instead of having to check for HTTPS using a RewriteCond %{HTTPS} =on for every redirect that can be either HTTP or HTTPS, I set an environment variable once with the value "http" or "https" if HTTP or HTTPS is being used for that request, and use that env variable in the RewriteRule.

Merging Notes

The order of merging is:

  1. <Directory> (except regular expressions) and .htaccess done simultaneously (with .htaccess, if allowed, overriding <Directory>)
  2. <DirectoryMatch> (and <Directory ~>)
  3. <Files> and <FilesMatch> done simultaneously
  4. <Location> and <LocationMatch> done simultaneously

Below is an artificial example to show the order of merging. Assuming they all apply to the request, the directives in this example will be applied in the order:

A > B > C > D > E

. 
<Location />
E
</Location>
<Files askapache.txt>

Technical Look at .htaccess

Source: Apache API notes

Per-directory configuration structures

Let's look out how all of this plays out in mod_mime.c, which defines the file typing handler which emulates the NCSA server's behavior of determining file types from suffixes. What we'll be looking at, here, is the code which implements the AddType and AddEncoding commands. These commands can appear in .htaccess files, so they must be handled in the module's private per-directory data, which in fact, consists of two separate tables for MIME types and encoding information, and is declared as follows:

table *forced_types;      /* Additional AddTyped stuff */
table *encoding_types;    /* Added with AddEncoding... */
mime_dir_config;

When the server is reading a configuration file, or <Directory> section, which includes one of the MIME module's commands, it needs to create a mime_dir_config structure, so those commands have something to act on. It does this by invoking the function it finds in the module's `create per-dir config slot', with two arguments: the name of the directory to which this configuration information applies (or NULL for srm.conf), and a pointer to a resource pool in which the allocation should happen.

(If we are reading a .htaccess file, that resource pool is the per-request resource pool for the request; otherwise it is a resource pool which is used for configuration data, and cleared on restarts. Either way, it is important for the structure being created to vanish when the pool is cleared, by registering a cleanup on the pool if necessary).

For the MIME module, the per-dir config creation function just ap_pallocs the structure above, and a creates a couple of tables to fill it. That looks like this:

void *create_mime_dir_config (pool *p, char *dummy)
mime_dir_config *new = (mime_dir_config *) ap_palloc (p, sizeof(mime_dir_config));
 
new->forced_types = ap_make_table (p, 4);
new->encoding_types = ap_make_table (p, 4);

Now, suppose we've just read in a .htaccess file. We already have the per-directory configuration structure for the next directory up in the hierarchy. If the .htaccess file we just read in didn't have any AddType or AddEncoding commands, its per-directory config structure for the MIME module is still valid, and we can just use it. Otherwise, we need to merge the two structures somehow.

To do that, the server invokes the module's per-directory config merge function, if one is present. That function takes three arguments: the two structures being merged, and a resource pool in which to allocate the result. For the MIME module, all that needs to be done is overlay the tables from the new per-directory config structure with those from the parent:

void *merge_mime_dir_configs (pool *p, void *parent_dirv, void *subdirv)
mime_dir_config *parent_dir = (mime_dir_config *)parent_dirv;
mime_dir_config *subdir = (mime_dir_config *)subdirv;
mime_dir_config *new =  (mime_dir_config *)ap_palloc (p, sizeof(mime_dir_config));
new->forced_types = ap_overlay_tables (p, subdir->forced_types, parent_dir->forced_types);
new->encoding_types = ap_overlay_tables (p, subdir->encoding_types, parent_dir->encoding_types);

As a note --- if there is no per-directory merge function present, the server will just use the subdirectory's configuration info, and ignore the parent's. For some modules, that works just fine (e.g., for the includes module, whose per-directory configuration information consists solely of the state of the XBITHACK), and for those modules, you can just not declare one, and leave the corresponding structure slot in the module itself NULL.

Command handling

Now that we have these structures, we need to be able to figure out how to fill them. That involves processing the actual AddType and AddEncoding commands. To find commands, the server looks in the module's command table. That table contains information on how many arguments the commands take, and in what formats, where it is permitted, and so forth. That information is sufficient to allow the server to invoke most command-handling functions with pre-parsed arguments. Without further ado, let's look at the AddType command handler, which looks like this (the AddEncoding command looks basically the same, and won't be shown here):

char *add_type(cmd_parms *cmd, mime_dir_config *m, char *ct, char *ext)
if (*ext == '.') ++ext;
ap_table_set (m->forced_types, ext, ct);

This command handler is unusually simple. As you can see, it takes four arguments, two of which are pre-parsed arguments, the third being the per-directory configuration structure for the module in question, and the fourth being a pointer to a cmd_parms structure. That structure contains a bunch of arguments which are frequently of use to some, but not all, commands, including a resource pool (from which memory can be allocated, and to which cleanups should be tied), and the (virtual) server being configured, from which the module's per-server configuration data can be obtained if required.

Another way in which this particular command handler is unusually simple is that there are no error conditions which it can encounter. If there were, it could return an error message instead of NULL; this causes an error to be printed out on the server's stderr, followed by a quick exit, if it is in the main config files; for a .htaccess file, the syntax error is logged in the server error log (along with an indication of where it came from), and the request is bounced with a server error response (HTTP error status, code 500).

The MIME module's command table has entries for these commands, which look like this:

command_rec mime_cmds[] =
{ "AddType", add_type, NULL, OR_FILEINFO, TAKE2, "a mime type followed by a file extension" },
{ "AddEncoding", add_encoding, NULL, OR_FILEINFO, TAKE2, "an encoding (e.g., gzip), followed by a file extension" },

The entries in these tables are:

  • The name of the command
  • The function which handles it a (void *) pointer, which is passed in the cmd_parms structure to the command handler --- this is useful in case many similar commands are handled by the same function.
  • A bit mask indicating where the command may appear. There are mask bits corresponding to each AllowOverride option, and an additional mask bit, RSRC_CONF, indicating that the command may appear in the server's own config files, but not in any .htaccess file.
  • A flag indicating how many arguments the command handler wants pre-parsed, and how they should be passed in. TAKE2 indicates two pre-parsed arguments. Other options are TAKE1, which indicates one pre-parsed argument, FLAG, which indicates that the argument should be On or Off, and is passed in as a boolean flag, RAW_ARGS, which causes the server to give the command the raw, unparsed arguments (everything but the command name itself). There is also ITERATE, which means that the handler looks the same as TAKE1, but that if multiple arguments are present, it should be called multiple times, and finally ITERATE2, which indicates that the command handler looks like a TAKE2, but if more arguments are present, then it should be called multiple times, holding the first argument constant.
  • Finally, we have a string which describes the arguments that should be present. If the arguments in the actual config file are not as required, this string will be used to help give a more specific error message. (You can safely leave this NULL).

Finally, having set this all up, we have to use it. This is ultimately done in the module's handlers, specifically for its file-typing handler, which looks more or less like this; note that the per-directory configuration structure is extracted from the request_rec's per-directory configuration vector by using the ap_get_module_config function.

Side notes --- per-server configuration, virtual servers, etc.

The basic ideas behind per-server module configuration are basically the same as those for per-directory configuration; there is a creation function and a merge function, the latter being invoked where a virtual server has partially overridden the base server configuration, and a combined structure must be computed. (As with per-directory configuration, the default if no merge function is specified, and a module is configured in some virtual server, is that the base configuration is simply ignored).

The only substantial difference is that when a command needs to configure the per-server private module data, it needs to go to the cmd_parms data to get at it. Here's an example, from the alias module, which also indicates how a syntax error can be returned (note that the per-directory configuration argument to the command handler is declared as a dummy, since the module doesn't actually have per-directory config data):

]]> AskApache.com

In part I: SEO Secrets of AskApache.com we talked about content and building a website to be your "SEO Base". This article discusses some advanced SEO concepts to get a site indexed, move your best pages higher in search results, and controlling the pagerank/seo-juice of your site. but relatively easy ways to control and tweak WHAT urls on your site are indexed, and HOW. I've heard some people refer to this as "controlling pagerank flow" and "controlling pagerank juice", basically we want our best pages to rank higher in the search engine results.

Big Picture: Going from no website to AskApache.com in less than a year can be accomplished by anyone with unique content and a resolve to avoid any shortcuts and take it one step at a time.

We want what Google wants, to provide the most relevant content for someone who is doing a search. Basically, you want every url on your site that has unique content to be included in the index. In other words, you have to think like a search engine!

The Goal of Google

Here's what I mean, Google approaches search with the overwhelming goal of bringing the content to a searcher that is the most-likely to be what that searcher is searching for. Another way of looking at it is something I read on Google...

Google's goal is to get you off of their site as fast as possible by providing you with exactly what you are looking for.

Think about SEO like this

If you search for htaccess tutorial for seo on Google, would you be more likely to visit a tutorial about using .htaccess for seo or a category page for htaccess articles? AskApache.com has both of those urls included in the index, but the article ranks higher than the category page, as it very well should.

Get Your URLS Indexed

Before I explain how I am able to help Google and other search engines rank my article pages higher than my category pages, we need to get the urls in the index or nothing will show up. There are many well-discussed methods for getting included in the index, so I'll just list a few that I use.

  1. Provide High-Quality original content, people will link to it
  2. Get a sitemap and use Google Webmaster Tools
  3. Publish an RSS/Atom Feed and ping the net when you publish a post
  4. Use robots.txt and robots meta tags

Your URLs in the index

Here's how to find out which of your pages are indexed.

  • Indexed pages in your site: site:
  • Pages that link to your site's front page: link:
  • The current cache of your site: cache:
  • Information about your site: info:
  • Pages that are similar to your site: related:

Break It Down

Yo homeslice! I didn't mean break dance.. I mean lets simplify AskApache in the context of getting our urls indexed high/low. Here's the stats: 1 Homepage, 206 Articles, 19 Pages, 31 Categories

1 Homepage

This page is generally the highest ranking page in the index, it should contain links to your best urls, and provide easy navigation

206 Specific Topic Articles

These are the article's (like this one) of AskApache.com and are the main source of search engine traffic. You want each url (if its a good article) to be ranked as high as possible. Some keys are to really make each article specific to a topic by using best-practice (X)HTML.

19 Static Pages

Most of these are pages like the online-tools hosted on this site, or other basic pages like about, contact us, site-map, etc.. Some of these you may want to rank very high ( like the /about/ page ) and some you may not want to even be included in the index.

31 Specific Topic Category Pages

These are tricky because they are generally just lists of articles from each category, which isn't specific enough to get much seach-engine-traffic, but is very useful to site visitors. I beefed up my category pages by adding additional information about the category topic in addition to excerpts of the articles.

Higher Pagerank = Higher Up in Search Results

So Googlebot and other search engine robots have these crazy complicated algorithms (many patented) that SEO Industry types may get caught up in and try to technically analyze them. I'm sure you've seen/read/heard the complicated advice that will always be pushed by many... advice like:

  • analyze the number of words in the description/title/1st paragraph/etc.
  • Make sure your "keyword" is sprinkled throughout the text every 10-30th word..
  • Other equally unexciting technical analysis

Now if you've had success with that then props to you, success is success, but I personally choose to completely ignore all that. The number 1 thing that the top search engines advise is to design your page for a Human Visitor, not a computer. The golden rule for me is how I would rank the page, not how some algorithm would.

Designing for a Human Visitor

This is a major factor in your site being at the top vs. nowhere. You design your HTML to be as minimal as possible (see source code for my homepage) and contain ONLY the neccessary elements. Above all, use semantically sound XHTML markup. (view source of W3C)

External CSS/Javascript

Get your javascript and CSS out of your HTML and use external files (like this site) ALWAYS! You should start with just the HTML, no css, no colors, no javascript, and THEN you add the .css and then you add the javascript.

Site Accessibility

Say your browser didn't have a mouse, didn't support images, css, javascript, or even colors! Your HTML should be structured such that your page is still easily readable and easy to navigate. You can use lynx, links, and many other terminal-based browsers to test for this... please see the Web Accessibility Initiative (WAI) for detailed info.

Web accessibility refers to the practice of making websites usable by people of all abilities and disabilities. When sites are correctly designed, developed and edited, all users can have equal access to information and functionality. For example, when a site is coded with semantically meaningful HTML, with textual equivalents provided for images and with links named meaningfully, this helps blind users using text-to-speech software and/or text-to-Braille hardware.

Controlling a URL's Pagerank

A few tools and techniques are available for controlling the "juice" or "pagerank" of your urls.

  1. Robots.txt
  2. Robots Meta Tags
  3. Links

Robots.txt

I've done quite a bit of research and experimentation with robots.txt files, which is a file located in the root of your website at http://www.askapache.com/robots.txt that is downloaded by all legitimate search engine spiders/bots and used as a Blacklist to prevent certain urls from being indexed. Here are a few of the articles on this site, which you may skip if you like as they don't illustrate the big-picture that I am going to discuss now.

How To Use Robots.txt

Even though robots.txt files are for whitelisting and blacklisting urls, I have found that they should only be used as an extreme form of blacklisting. When you Disallow a url in your robots.txt file, that means most search engine bots won't even LOOK at the url. As you can see in the below example, I only disallow urls that shouldn't ever be LOOKED at. The real powertool is the robots meta tag.

User-agent: *
Disallow: /cgi-bin
Disallow: /wp-admin
Disallow: /wp-includes
Disallow: /wp-content
 
Sitemap: http://www.askapache.com/sitemap.xml

Robots Meta Tag

Ok I'm really trying to simplify, because what you should understand is the big-picture. Every page can have a robots meta tag in the header, and this robots meta tag can tell the search-engine to index/not-index AND follow/not-follow. Here are some examples:

<meta name="robots" content="index" />
<meta name="robots" content="noindex" />
<meta name="robots" content="noindex,follow" />
<meta name="robots" content="index,nofollow" />

content="index" / noindex

index means the search engine is free to index, archive, cache, and follow the page whereas noindex means DO NOT include this page in the search engine results.

content="follow" / nofollow

follow means the search engine is free to LOOK at the page and follow the links on the page whereas nofollow means DO NOT follow the links on the page.

WordPress Auto-Robots meta tag code

Just add this to any plugin file and it will add the right robots meta tag to your site.. tweak to taste.

function askapache_robots_header(){
 global $wpdb;
 
 $robot = '<meta name="robots" content="noindex,follow,nocache,noarchive" />';
 
 if ( is_paged() || is_search() || is_404() || is_author() || is_tag() )
   $robot = '<meta name="robots" content="noindex,follow" />';
 elseif ( is_home() || is_front_page() || is_single() )
   $robot = '<meta name="robots" content="follow,index" />';
 elseif ( is_category() || is_page() )
   $robot = '<meta name="robots" content="follow" />';
 
 echo $robot . "\n";
}
add_action( 'wp_head', 'askapache_robots_header' );

Links

External and Internal Links are the crux of SEO. It's important to start FIRST on your Internal Links and linking structure... Once you are satisfied that the correct pages are indexed and ranked appropriately, then you can begin to look at external links.

  • The fewer links on a page, generally the better.
  • If every page of your site points to the same url on your site, pagerank goes up from the number of internal links.
  • Use of the rel, title, alt attribute semantically is very helpful. (next, prev, index)
  • Put your best links higher up in the XHTML, and put helpful/solid links at the end.
  • You can add rel="nofollow" to links that you dont want followed.

The web has gotten to be so full of malicious/non-helpful SEO activity that I recommend developing your content NOT external links. If you want to do this right and provide great content that makes search engine users happy and makes the web better, then explore this blog and develop content until the next article in this series, where I'll show you how to make your site explode.

CSS Classes Toolbox .classAs a Professional Web Developer and Designer, CSS is by far one of the most useful tools I use. Moving from one web site to the next is made easier by having a CSS Toolbox containing some default CSS Classes that you use over and over again. Here are 10 of my favorite CSS Classes.

What are Your favorite CSS Classes? Please share your tips!

Universal CSS .Classes

Most of these are what I like to think of as "actionable" classes, IOW, they aren't just color classes or font-size classes.

  1. .S {display:block; visibility:visible;} - Shows the element.
  2. .H {display:none; visibility:hidden;} - Hides the element.
  3. .VV {visibility:visible;} - Makes the element visible.
  4. .VH {visibility:hidden;} - Hides an element but still takes up space, not fullly hidden like .H
  5. .FR {float:right;} - Floats the element to the right.
  6. .FL {float:left;} - Floats the element to the left.
  7. .DI {display:inline;} - Changes the display type to "inline".
  8. .DB {display:block;} - Makes the element a block-level element.
  9. .C {clear:both; padding:0; margin:0; line-height:2em; font-size:10px; border-bottom:1px solid #FFF;} - Clears floated elements.
  10. .CENT {margin:0 auto;} - Makes block element centred.

Please note that these classes are meant only to show what can be done with CSS, I wrote this post for CSS guru's and up and coming gurus. Sometimes I assume everyone reading my blog know as much as I do about what I'm writing about, so I skip almost all explanation and skip to the code. Basically stick to the W3C's recommendations and try not to use classes inline unless its for something specific. Most of these classes are very useful for use in javascript as well using the element.className='S' method.

Universal CSS Classes Example

<br class="C" /> - clears any block level element.
<hr class="C VH" /> - Its still a block-level element, so it correctly clears floated elements and is a semantic page separator.
<img class="FR" src="/1.gif" alt="" /> - this image will float to the right.
<p class="CENT"> - the p is centred (if width isn't 100%;).

Think you are such a CSS/semantics guru that using classes is below you? Ridiculous! Classes are extremely helpful when used properly and not in excess. Surely you don't think you know more than Eric Meyer or the W3C... please view their source code, and try to loosen up while your at it ;)
