3 Ways to Serve PDF Files using Htaccess Cookies, Headers, Rewrites

AskApache — Sun, 21 Aug 2011 03:07:53 +0000

FYI, using the Mod_Rewrite Variables Cheatsheet makes this example, and all advanced .htaccess code easier to understand. This demo lets you set a cookie with 1 of 3 values, then you just request the pdf file with a normal link click and get 1 of 3 different responses. This is accomplished with a nice bit of .htaccess code.

As I explain the htaccess code that achieves this, keep in mind this is merely one simple application for this code. It's much more advanced than your basic htaccess trick, notice how this htaccess acts like a php script, very unusual.. I really wanted to share this trick after I created it for one of my clients because this is the tip of the iceberg. Another use would be to display an alternate style sheet depending on a users theme preference. The coolest thing is that it uses multiple advanced .htaccess ideas. This code uses mod_headers to set the Content-Disposition header for forcing a download and uses mod_rewrite to: Send different Content-Type headers, Check the value of a cookie, Set environment variables for use later by mod_headers header directive

Set PDF Viewing Mode - Make a selection, then click the view pdf button.

Inline Download Save As View PDF using selected mode »

What's Going On

There are 3 different ways for a server to send a pdf file in response to a request for one. This causes 3 different ways to open/view the pdf file in the clients browser.

The browser display's a "Save File As" dialog, allowing you to save the file or open.
The browser opens the pdf file "Inline", opening the pdf file in the browser like a web page.
The browser "Downloads" the pdf file automatically as an "Attachment" and then causes an external pdf reader program like adobe reader to open the file.

Some people prefer to have the option of saving the file to view later, some prefer opening it with an external program, and some just like the pdf file to load right in the browser... The point is that by using .htaccess, we can let them choose any of the 3 methods and save their preference for all further pdf files requested from our site by that user.

How It Works

When you click on one of the 3 demo buttons above, "Inline", "Save As", or "Download", a cookie named askapache_pdf is saved in your browser using the javascript below, with the value being set to which button you clicked. Then when you request the pdf file the .htaccess code below uses mod_rewrite to read the value of the askapache_pdf cookie, and depending on which was your preference it will send alternate HTTP Headers that control how your browser handles the file.

Unique HTTP Headers Returned

When it comes down to it, the following information is the 3 modes. Notice each one is different, because these headers are the only thing controlling how your browser handles the file.

Save As Mode (askapache_pdf=s)

Content-Disposition: attachment
Content-Type: application/pdf

Inline Mode (askapache_pdf=i)

Content-Type: application/pdf

Download Mode (askapache_pdf=a)

Content-Type: application/octet-stream

Htaccess Demo File

For the demo I created the folder /storage/pdf/ and this is the .htaccess file at /storage/pdf/.htaccess

The default Content-Type for .pdf files. This will make .pdf files default Content-Type header have the value 'application/pdf' - but the default can be overridden by using RewriteRule with the [T='different/type']

AddType application/pdf .pdf

Turn on the rewrite engine if its already on you dont need this

RewriteEngine On

Skip RewriteRules if not .pdf request, like autoindexing. The next [2] RewriteRule directives are specific for .pdf files so if the filename requested does not end in .pdf then the [S=2] instructs the next 2 RewriteRule directives to be completely skipped.

RewriteRule !.*\.pdf$ - [S=2]

The first RewriteCond checks to see if the askapache_pdf cookie is NOT set. The second RewriteCond checks to see if the askapche_pdf cookie has the value of s, which is the value corresponding to someone clicking the "Save As" button.

The [NC,OR] flag means that if the cookie askapache_pdf does not exist, OR (next cond) if the askapache_pdf cookie does exist and is set to 's' then process the RewriteRule. If neither cond is true the rewriterule is skipped.

If one of the RewriteCond is true, then the RewriteRule is processed. The RewriteRule applies to any/all requests (.*) but doesn't rewrite anything (-) This RewriteRule sets an Apache environment variable ASKAPACHE_PDFS to have the value of 1 if either rewritecond is true. The variable can be checked by any directives following the rewriterule in the whole htaccess file. The ASKAPACHE_PDFS ends in S because if this variable exists then it means the users preference is 'Save As'

Notice that if the user requested the pdf file without selecting a preference i.e. no cookie exists, then the ASKAPACHE_PDFS variable is still set. This just lets us pick the default preference for them, in this example the default is 'Save As'

RewriteCond %{HTTP_COOKIE} !^.*askapache_pdf.*$ [NC,OR]
RewriteCond %{HTTP_COOKIE} ^.*askapache_pdf=s.*$ [NC]
RewriteRule .* - [E=ASKAPACHE_PDFS:1]

The RewriteCond checks the askapache_pdf cookie for the value 'a' which 'a' represents 'Download'

If the cookies value is 'a' then the RewriteRule overrides the default Content-Type from 'application/pdf' set with AddType earlier, to 'application/octet-stream', which is a special content-type that tells the browser that the file cannot be loaded by the browser 'Inline', but must be saved which will be opened by an external viewer depending on browser configuration and plugins.

RewriteCond %{HTTP_COOKIE} ^.*askapache_pdf=a.*$
RewriteRule .* - [T=application/octet-stream]

This is superfly. If the cookie/users-preference was 'Save As' (s) then the RewriteRule above the last one set the environment variable ASKAPACHE_PDFS to have the value 1. The Header directive here is ONLY processed in that variable ASKAPACHE_PDFS exists. That is what the end 'env=ASKAPACHE_PDFS' does, it is the condition that must be met or the Header directive is skipped. If the ASKAPACHE_PDFS environment variable set by RewriteRule does exist then the header directive adds the header 'Content-Disposition: attachment' to the normal Response Headers. The 'Content-Disposition: attachment' header instructs your browser to present you with the 'Save As' dialog box allowing you to choose whether you want to save or open.

Header set Content-Disposition "attachment" env=ASKAPACHE_PDFS

Javascript used by Demo

The best place for javascript is quirksmode, here is a definitive article on setting, reading, parsing, etc.. COOKIES.

Note, I now prefer using jQuery over my AAJS javascript library. Also, the whole using cookies aspect is just to highlight some advanced htaccess, you can accomplish this much easier without javascript or cookies.

if(!gi('pdfr'))return;
var pdfr=gi('pdfr');
var cval=getCookie('askapache_pdf');
 
if(cval=='i'){pdfr.innerHTML='Currently set to "Inline".';}
else if(cval=='a'){pdfr.innerHTML='Currently set to "Download" mode.';}
else if(cval=='s'){pdfr.innerHTML='Currently set to "Save As" mode.';}
 
addMyEvent(gi('pdfi'),"mousedown",function(){
  setCookie("askapache_pdf", "i", "", "/", "www.askapache.com"); gi('pdfr').innerHTML = 'Changed mode to "Inline".'; return false; });
addMyEvent(gi('pdfa'),"mousedown",function(){
  setCookie("askapache_pdf", "a", "", "/", "www.askapache.com"); gi('pdfr').innerHTML = 'Changed mode to "Download".'; return false; });
addMyEvent(gi('pdfs'),"mousedown",function(){
  setCookie("askapache_pdf", "s", "", "/", "www.askapache.com"); gi('pdfr').innerHTML = 'Changed mode to "Save As".'; return false; });

Alternative Method - No Cookies + PHP

This is what I came up with first for my client, and then while programming the php I noticed.. Hey! I think I can do the same thing using .htaccess, which would save me on cpu/memory/potential security/etc.. but this works great too. Though you will need to hack the code to get it working probably..

Note that the .htaccess rewrite code I used here used FILENAME-i.pdf or FILENAME-s.pdf to pass the preference to the pdf-dl.php script, it also worked for FILENAME.pdf?i=i

pdf-dl.php

Alternate Method .htaccess

Deny direct request to pdf-dl.php file

RewriteCond %{THE_REQUEST} ^.*pdf-dl\.php.*$ [NC]
RewriteRule .* - [F]

Handle PDF files named anything-i.pdf as inline

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ([^/]*)-i\.pdf$  /cgi-bin/pdf-dl.php?i=i&file=%{DOCUMENT_ROOT}/storage/pdf/$1.pdf [L,NC,QSA,S=1]

Handle PDF files without -i.pdf as attachments

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ([^/]*)\.pdf$  /cgi-bin/pdf-dl.php?file=%{DOCUMENT_ROOT}/storage/pdf/$1.pdf [L,NC,QSA]

Htaccess Rewrites – Rewrite Tricks and Tips

AskApache — Sun, 10 Apr 2011 14:05:00 +0000

AskApache.com

Htaccess Rewrites are enabled by using the Apache module mod_rewrite, which is one of the most powerful Apache modules and features availale. Htaccess Rewrites through mod_rewrite provide the special ability to Rewrite requests internally as well as Redirect request externally.

When the url in your browser's location bar stays the same for a request it is an internal rewrite, when the url changes an external redirection is taking place. This is one of the first, and one of the biggest mental-blocks people have when learning about mod_rewrite... But I have a secret weapon for you to use, a new discovery from years of research that makes learning mod_rewrite drastically quicker and easier. It truly does or I wouldn't be saying so in the introduction of this article.

Despite the tons of examples and docs, mod_rewrite is voodoo. Damned cool voodoo, but still voodoo.
-- Brian Moore

Note: After years of fighting to learn my way through rewriting urls with mod_rewrite, I finally had a breakthrough and found a way to outsmart the difficulty of mod_rewrite that I just couldn't seem to master. The Mod_Rewrite RewriteCond/RewriteRule Variable Value Cheatsheet is the one-of-a-kind tool that changed the game for me and made mod_rewriting no-harder than anything else.

So keep that mod_rewrite reference bookmarked and you will be able to figure out any RewriteRule or RewriteCond, an amazing feat considering it took me a LONG time to figure this stuff out on my own. But that was before the craziness, one of the most challenging and productive .htaccess experiments I've done... An experiment so ILL it's sick like a diamond disease on your wrist! $$$. That mod_rewrite experiment/tutorial was the culmination of many different advanced mod_rewrite experiments I had done in the past and included most of my very best .htaccess tricks. With the cheatsheet it's no longer Voodoo.. Its just what you do. Now lets dig in!

If you really want to take a look, check out the mod_rewrite.c and mod_rewrite.h files.

Be aware that mod_rewrite (RewriteRule, RewriteBase, and RewriteCond) code is executed for each and every HTTP request that accesses a file in or below the directory where the code resides, so it's always good to limit the code to certain circumstances if readily identifiable.

For example, to limit the next 5 RewriteRules to only be applied to .html and .php files, you can use the following code, which tests if the url does not end in .html or .php and if it doesn't, it will skip the next 5 RewriteRules.

RewriteRule !\.(html|php)$ - [S=5]
RewriteRule ^.*-(vf12|vf13|vf5|vf35|vf1|vf10|vf33|vf8).+$ - [S=1]

.htaccess rewrite examples should begin with:

Options +FollowSymLinks
 
RewriteEngine On
RewriteBase /

Require the www

Options +FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www\.askapache\.com$ [NC]
RewriteRule ^(.*)$ http://www.askapache.com/$1 [R=301,L]

Loop Stopping Code

Sometimes your rewrites cause infinite loops, stop it with one of these rewrite code snippets.

RewriteCond %{REQUEST_URI} ^/(stats/|missing\.html|failed_auth\.html|error/).* [NC]
RewriteRule .* - [L]
 
RewriteCond %{ENV:REDIRECT_STATUS} 200
RewriteRule .* - [L]

Cache-Friendly File Names

This is probably my favorite, and I use it on every site I work on. It allows me to update my javascript and css files in my visitors cache's simply by naming them differently in the html, on the server they stay the same name. This rewrites all files for /zap/j/anything-anynumber.js to /zap/j/anything.js and /zap/c/anything-anynumber.css to /zap/c/anything.css

RewriteRule ^zap/(j|c)/([a-z]+)-([0-9]+)\.(js|css)$ /zap/$1/$2.$4 [L]

SEO friendly link for non-flash browsers

When you use flash on your site and you properly supply a link to download flash that shows up for non-flash aware browsers, it is nice to use a shortcut to keep your code clean and your external links to a minimum. This code allows me to link to site.com/getflash/ for non-flash aware browsers.

RewriteRule ^getflash/?$ http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash [NC,L,R=307]

Removing the Query_String

On many sites, the page will be displayed for both page.html and page.html?anything=anything, which hurts your SEO with duplicate content. An easy way to fix this issue is to redirect external requests containing a query string to the same uri without the query_string.

RewriteCond %{THE_REQUEST} ^GET\ /.*\;.*\ HTTP/
RewriteCond %{QUERY_STRING} !^$
RewriteRule .* http://www.askapache.com%{REQUEST_URI}? [R=301,L]

Sending requests to a php script

This .htaccess rewrite example invisibly rewrites requests for all Adobe pdf files to be handled by /cgi-bin/pdf-script.php

RewriteRule ^(.+)\.pdf$  /cgi-bin/pdf-script.php?file=$1.pdf [L,NC,QSA]

Setting the language variable based on Client

For sites using multiviews or with multiple language capabilities, it is nice to be able to send the correct language automatically based on the clients preferred language.

RewriteCond %{HTTP:Accept-Language} ^.*(de|es|fr|it|ja|ru|en).*$ [NC]
RewriteRule ^(.*)$ - [env=prefer-language:%1]

Deny Access To Everyone Except PHP fopen

This allows access to all files by php fopen, but denies anyone else.

RewriteEngine On
RewriteBase /
RewriteCond %{THE_REQUEST} ^.+$ [NC]
RewriteRule .* - [F,L]

If you are looking for ways to block or deny specific requests/visitors, then you should definately read Blacklist with mod_rewrite. I give it a 10/10

Deny access to anything in a subfolder except php fopen

This can be very handy if you want to serve media files or special downloads but only through a php proxy script.

RewriteEngine On
RewriteBase /
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^/]+)/.*\ HTTP [NC]
RewriteRule .* - [F,L]

Require no www

Options +FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^askapache\.com$ [NC]
RewriteRule ^(.*)$ http://askapache.com/$1 [R=301,L]

Check for a key in QUERY_STRING

Uses a RewriteCond Directive to check QUERY_STRING for passkey, if it doesn't find it it redirects all requests for anything in the /logged-in/ directory to the /login.php script.

RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} !passkey
RewriteRule ^/logged-in/(.*)$ /login.php [L]

Removes the QUERY_STRING from the URL

If the QUERY_STRING has any value at all besides blank than the?at the end of /login.php? tells mod_rewrite to remove the QUERY_STRING from login.php and redirect.

RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} .
RewriteRule ^login.php /login.php? [L]

Fix for infinite loops

An error message related to this isRequest exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.or you may seeRequest exceeded the limit,probable configuration error,Use 'LogLevel debug' to get a backtrace, orUse 'LimitInternalRecursion' to increase the limit if necessary

RewriteCond %{ENV:REDIRECT_STATUS} 200
RewriteRule .* - [L]

External Redirect .php files to .html files (SEO friendly)

RewriteRule ^(.*)\.php$ /$1.html [R=301,L]

Internal Redirect .php files to .html files (SEO friendly)

Redirects all files that end in .html to be served from filename.php so it looks like all your pages are .html but really they are .php

RewriteRule ^(.*)\.html$ $1.php [R=301,L]

block access to files during certain hours of the day

Options +FollowSymLinks
RewriteEngine On
RewriteBase /

This module uses a rule-based rewriting engine (based on a regular-expression parser) to rewrite requested URLs on the fly. It supports an unlimited number of rules and an unlimited number of attached rule conditions for each rule, to provide a really flexible and powerful URL manipulation mechanism. The URL manipulations can depend on various tests, of server variables, environment variables, HTTP headers, or time stamps. Even external database lookups in various formats can be used to achieve highly granular URL matching.

This module operates on the full URLs (including the path-info part) both in per-server context (httpd.conf) and per-directory context (.htaccess) and can generate query-string parts on result. The rewritten result can lead to internal sub-processing, external request redirection or even to an internal proxy throughput.

Further details, discussion, and examples, are provided in the detailed mod_rewrite documentation.

This article is meant to prepare us for the advanced mod_rewrite examples that are soon to be published. The upcoming article is going to be examples using mod_rewrite to achieve some crazy stuff... Here the focus is on identifying mod_rewrite variables and defining the limits of the module by checking the mod_rewrite source code.

For a broader mod_rewrite cheat sheet, check this printable cheat sheet.

Directives in Mod_Rewrite

RewriteEngine

RewriteEngine on|off

On or Off to enable or disable (default) the whole rewriting engine

RewriteOptions

RewriteOptions Options

List of option strings to set

RewriteBase

RewriteBase URL-path

the base URL of the per-directory context

RewriteCond

RewriteCond TestString CondPattern

an input string and a to be applied regexp-pattern

RewriteRule

RewriteRule Pattern Substitution [flags]

an URL-applied regexp-pattern and a substitution URL

RewriteMap

RewriteMap MapName MapType:MapSource

a mapname and a filename

RewriteLock

RewriteLock file-path

the filename of a lockfile used for inter-process synchronization

RewriteLog

RewriteLog file-path

the filename of the rewriting logfile

RewriteLogLevel

RewriteLogLevel Level

the level of the rewriting logfile verbosity (0=none, 1=std, .., 9=max)

RewriteRule Flags

C

Using the [Chain], or [C] flag, allows you to indicate that several rules should be chained together as a single logical transation. This is usually used when a transformation is sufficiently complicated to warrant breaking into several smaller steps.

CO

cookie|CO=Name:Value:Domain[:Lifetime[:Path]]

This sets a cookie on the client's browser. The cookie's name is specified by NAME and the value is VAL. The domain field is the domain of the cookie, such as '.apache.org',the optional lifetime is the lifetime of the cookie in minutes, and the optional path is the path of the cookie.

E

'env|E=VAR:VAL' (set environment variable)

RewriteRule (root|cmd)\.exe - [E=worm:nimda]

F

'forbidden|F' (force URL to be forbidden)

G

'gone|G' (force URL to be gone)

H

'handler|H=Content-handler' (force Content handler)

L

'last|L' (last rule)

N

'next|N' (next round)

NC

'nocase|NC' (no case)

NE

'noescape|NE' (no URI escaping of output)

NS

'nosubreq|NS' (not for internal sub-requests)

P

'proxy|P' (force proxy)

PT

'passthrough|PT' (pass through to next handler)

QSA

'qsappend|QSA' (query string append)

R

'redirect|R  [=code]' (force redirect)

S

'skip|S=num' (skip next rule(s))

This flag forces the rewriting engine to skip the next num rules in sequence, if the current rule matches. Use this to make pseudo if-then-else constructs: The last rule of the then-clause becomes skip=N, where N is the number of rules in the else-clause. (This is not the same as the 'chain|C' flag!)

T

'type|T=MIME-type' (force MIME type)

Force the MIME-type of the target file to be MIME-type. This can be used to set up the content-type based on some conditions. For example, the following snippet allows .php files to be displayed by mod_php if they are called with the .phps extension:

Rules and Conditions Processing Order

The Pattern of the RewriteRule (^/.*$) is checked first.
If the pattern matches, then the RewriteCond's are checked.
If the RewriteConditions also match, the RewriteRule is applied.

URL Rewriting Module

This module uses a rule-based rewriting engine (based on a regular-expression parser) to rewrite requested URLs on the fly.

It supports an unlimited number of additional rule conditions (which can operate on a lot of variables, even on HTTP headers) for granular matching and even external database lookups (either via plain text tables, DBM hash files or even external processes) for advanced URL substitution.

It operates on the full URLs (including the PATH_INFO part) both in per-server context (httpd.conf) and per-dir context (.htaccess) and even can generate QUERY_STRING parts on result. The rewriting result finally can lead to internal subprocessing, external request redirection or even to internal proxy throughput.

This module was originally written in April 1996 and gifted exclusively to the The Apache Software Foundation in July 1997 by

Ralf S. Engelschall rse [at] engenschall.com

Actual Htaccess Files from My Server

AskApache — Sat, 17 Apr 2010 15:06:22 +0000

AskApache.com

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

# DirectoryIndex: sets the file that Apache will serve if a directory

# 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.)

# Commonly used filename extensions to character sets. You probably

#
# 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

# 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...)

### 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.
#

    Order allow,deny
    Deny from all
  Satisfy All

 
#
# 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

Advanced WordPress wp-config.php Tweaks

AskApache — Wed, 03 Mar 2010 08:23:37 +0000

AskApache.com

The bottom line for this article is that I want to make WordPress as fast, secure, and easy to install, run, and manage because I am using it more and more for client production sites, I will work for days in order to solve an issue so that I never have to spend time on that issue again. Time is money in this industry and that is ultimately (time) what there is to gain by tweaking WordPress.

Note: I spent no time on readability, this is primarily a read the code and figure it out article.. This is for advanced users looking for a reference or discussion and for those of you looking to advance. Feedback would be great if you make it that far..

For a better handle on the way I like to structure web site directories, see Optimize a Website for Speed, Security, and Easy Management but note it is a bit outdated compared to what I'm doing now. I don't have the luxury of using only one type of server, or hosting provider anymore, so I have been working towards making things even more portable in order to move from host to host from server to server without issues i.e. my portable .bash_profile.

So I've been basically experimenting various ways to accomplish that and thought I would share what I am currently doing for my benefit and hopefully get some input. All of my WP installs run the development version, and one main idea with my setups is that upgrading is automated. So I really keep the WordPress install clean and use plugins and wp-config.php to do all the customization.

Portability - Hands-free upgrades and easy to move
Security - Additional security and protection
Speed - Less CPU and Disk I/O
Customization - All my favorite customizations

wp-config.php

These are the main settings I use.. Seriously this is more like an interactive article, because to understand it you will need to do some code grepping. You may want to grab a jolt.

ASKAPACHE_ROOT

The ASKAPACHE_ROOT variable is just a better way for me to be able to include and access all the different files in my site tree. For instance, in my non-wp php files, I can do this:

!defined('ASKAPACHE_ROOT') && require $_SERVER['DOCUMENT_ROOT'] . '/wp-config.php';
include(ASKAPACHE_ROOT . '/includes/custom-download.inc.php');

ASKAPACHE_LOCK

This is one of my all-time favorite hacks, that I think is one of the most useful methods I employ as a web developer. This allows me to use far-future-expire headers for optimum caching, while still forcing browsers to re-validate every day or so automatically, or forcing them to re-validate whenever I change the suffix. This takes advantage of the mod_rewrite trick that I use on EVERY site I run, definately worth learning. Because I practice best-practice web-standards, for every web site I create a single css file and javascript file, which I then add to the template like:

 Settings > General panel.

Debugging WordPress

One of my secrets for getting really good at this stuff is to master debugging. There is really not ever a time when I am working on a site that I don't have color-highlighted logs scrolling automatically in an ssh window. It's really almost impossible to fix problems with wordpress or do any kind of advanced anything without being able to view debugging info. At first I relied heavily on a custom php.ini being available on the server, but after having to deal with many hosts who don't allow php.ini files I now rely completely on setting values using ini_set for ultimate portability. Detailed towards the end of this article and is also included in this wp-config.php

/**#@+
 * DEBUGGING STUFF
 */
/** display of notices during development. if false, error_reporting is E_ERROR | E_WARNING | E_PARSE | E_USER_ERROR | E_USER_WARNING | E_RECOVERABLE_ERROR otherwise E_ALL */

!defined('WP_DEBUG_DISPLAY') && define('WP_DEBUG_DISPLAY', false);

Ultimate Security Tweaks

Well, ultimate for WP's built-in keys and password functions, this is all for wp-config.php keep in mind. This is a very neccessary and recommended step, and is one of the only things I modify for each new installation.

Security KEYS

If like me you are familiar with password-cracking software like John the ripper, rainbow hash tables, l0pht-crack, etc.. then you will like to know that you can specify your own keys and salts for the encryption used by WP. They are AUTH_KEY, AUTH_SALT, SECURE_AUTH_KEY, SECURE_AUTH_SALT, LOGGED_IN_KEY, LOGGED_IN_SALT, NONCE_KEY, NONCE_SALT, SECRET_KEY and SECRET_SALT.

A random and long key gives you better encryption, and exponentially increasing that is using a random and long salt for the encryption. Encryptions with known salts are incredibly easy to decrypt compared to encryptions with secure salts, because the salt + key individually need to be guessed in order to find a matching hash, vs. just the key if the salt is known. See: Locating weak passwords.

A secret key is a hashing salt which makes your site harder to hack and access harder to crack by adding random elements to the password.

In simple terms, a secret key is a password with elements that make it harder to generate enough options to break through your security barriers. A password like "password" or "test" is simple and easily broken. A random, unpredictable password such as "88a7da62429ba6ad3cb3c76a09641fc" takes years to come up with the right combination.

For more information on the technical background and breakdown of secret keys and secure passwords, see:

I like to use the WordPress.org secret-key service 4 times. That's because for each key and salt I like to do: (1 key from api +random keyboard input+1 key from api).

/**#@+
 * Authentication Unique Keys.
 *
 * Change these to different unique phrases!
 * You can generate these using the {@link https://api.wordpress.org/secret-key/1.1/ WordPress.org secret-key service}
 * You can change these at any point in time to invalidate all existing cookies.
 * This will force all users to have to log in again.
 *
 * @since 2.6.0
 *
 * Get salt to add to hashes to help prevent attacks.
 *
 * The secret key is located in two places: the database in case the secret key
 * isn't defined in the second place, which is in the wp-config.php file. If you
 * are going to set the secret key, then you must do so in the wp-config.php
 * file.
 *
 * The secret key in the database is randomly generated and will be appended to
 * the secret key that is in wp-config.php file in some instances. It is
 * important to have the secret key defined or changed in wp-config.php.
 *
 * If you have installed WordPress 2.5 or later, then you will have the
 * SECRET_KEY defined in the wp-config.php already. You will want to change the
 * value in it because hackers will know what it is. If you have upgraded to
 * WordPress 2.5 or later version from a version before WordPress 2.5, then you
 * should add the constant to your wp-config.php file.
 *
 * Below is an example of how the SECRET_KEY constant is defined with a value.
 * You must not copy the below example and paste into your wp-config.php. If you
 * need an example, then you can have a
 * {@link https://api.wordpress.org/secret-key/1.1/ secret key created} for you.
 *
 * Salting passwords helps against tools which has stored hashed values of
 * common dictionary strings. The added values makes it harder to crack if given
 * salt string is not weak.
 *
 * @since 2.5
 * @link https://api.wordpress.org/secret-key/1.1/ Create a Secret Key for wp-config.php
 *
 * @return string Salt value from either 'SECRET_KEY' or 'secret' option

/**#@-*/

Using SSL for Admin and Login

SSL is kinda required from my point of view, it is just way to easy to sniff data off the wire otherwise. At least with SSL you force them to use tools like burpsuite, paros proxy, webscarab, etc..

/** @since 2.6.0  */
!defined('FORCE_SSL_ADMIN') && define('FORCE_SSL_ADMIN', true);
 
/** @since 2.6.0  */
!defined('FORCE_SSL_LOGIN') && define('FORCE_SSL_LOGIN', true);

Mod_Rewrite to Force SSL

This is pretty cool, it forces non-https for all urls except for /wp-admin and wp-login.php, which both require https. It also checks for the logged_in_cookie, and if that is present in the request then it doesn't force non-https. Kinda confusing if you don't have a mod_rewrite cheatsheet.

RewriteCond %{THE_REQUEST} ^$ [OR]
RewriteCond %{REQUEST_URI} ^/(wp-admin|wp-login\.php).*$ [NC,OR]
RewriteCond %{HTTP_COOKIE} ^.*wp_li_sadfsdfasdf11b361cdsdfasdfasd=.*$ [NC]
RewriteRule .* - [S=1]
 
RewriteCond %{HTTPS} =on [OR]
RewriteCond %{HTTP_HOST} !^www\.askapache\.com$ [NC]

File System Permissions

Cookies!

There's always a little comfort in having non-default cookies for security (against auto-bots), and using shorter names also means smaller HTTP Packets.

WordPress Database

This is usually the only thing I have to manually edit when creating a new site, unless I just use the same DB and modify the $table_prefix, (farther down). I run everything I possibly can in UTF-8, but if you don't already know alot about character sets, wow it is one of the most confusing things so you may want to save learning about that topic for another day. Otherwise the following are helpful (and show how confusing character sets are!)

If you ever setup WP to use the builtin membership features, make sure you learn about the CUSTOM_USER_TABLE and CUSTOM_USER_META_TABLE constants, I've found them very helpful.

/**#@+
 * MySQL settings
 */
/** The name of the database for WordPress */
define('DB_NAME', 'askapachewpblog75');
 
/** The username to access the database */
define('DB_USER', 'askapache245d');
 
/** The password for the username to access the database */
define('DB_PASSWORD', 'asdfklj2340');
 
/** The hostname to connect to the database at */
define('DB_HOST', 'mysql.askapache.com');
 
/** The charset of the database */
define('DB_CHARSET', 'utf8');
 
/** The collation of the database */
define('DB_COLLATE', 'utf8_general_ci');

$table_prefix

The $table_prefix is the value placed in the front of your database tables. Change the value if you want to use something other than wp_ for your database prefix. Typically this is changed if you are installing multiple WordPress blogs in the same database, and also for enhanced security.

Its a safe and good idea to change this value pre-installation to add more security to your WordPress blog. Exploits attempted against your WordPress blog by malicious crackers often are built with the premise that your blog uses the prefix wp_, by changing the value you mitigate some attack vectors.

/**
 * WordPress Database Table prefix.
 *
 * You can have multiple installations in one database if you give each a unique
 * prefix. Only numbers, letters, and underscores please!
 */
$table_prefix  = 'ar15_';
 
/** CUSTOM_USER_TABLE and CUSTOM_USER_META_TABLE are used to designated that the user and usermeta tables normally utilized by WordPress are not used, instead these values/tables are used to store your user information. */
//!defined('CUSTOM_USER_TABLE') && define('CUSTOM_USER_TABLE', $table_prefix . 'my_users');
//!defined('CUSTOM_USER_META_TABLE') && define('CUSTOM_USER_META_TABLE', $table_prefix . 'my_usermeta');

Sessions are slow

So I only use sessions when I have a specific use... In this case I need sessions only when one of the tools in the /online-tools/ directory is being used. And that is for the captcha image. In the future I won't ever use sessions.

if(preg_match( '#^/online-tools/#',$_SERVER['REQUEST_URI'])) session_start();

Include Custom Files

Sure you could use the my-hacks.php that WP allows, or you can just stick your functions in your TEMPLATEPATH/functions.php file, but they are executed only after the wp-settings.php file, which may be too late for your file.

In the past I've also used the auto_prepend_file settings to run my script before anything (index.php) but I ran into some issues on different hosts, and it wasn't as portable.

This is useful because you can have a file with globally available functions that you can use in non-WP areas as well as WP areas. I am moving away from this more and more as I learn more about classes and build plugins instead for portability.

include_once ASKAPACHE_ROOT . '/includes/myfunctions.inc';
 
/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-settings.php');
?>

Some Useful PHP

I am constantly trying to make my sites and code more portable, so I am using plugins alot more to accomplish things that I use to do with separate php. Here are some examples of minimal php.

add_filter("the_generator", create_function('$a','return "";'));
add_filter('the_content', create_function('$a', 'return ((is_feed())? $a."".get_the_title()." originally appeared on ".get_bloginfo("name")."." : $a);'), 99999);
add_filter('excerpt_length', create_function('$a', 'return 300;'),99);
add_filter('excerpt_more', create_function('$a', 'return "…";'),99);
add_action( 'wp_head', create_function('$a','echo "\n";'), 95 );
add_action( 'wp_head', create_function('$a','echo "\n";'), 96 );
add_action( 'wp_head', create_function('$a','echo "\n";'), 97 );
add_action( 'wp_head', create_function('$a','echo "\n";'), 98 );
add_action( 'wp_head', create_function('$a','echo "\n";'), 99 );

Debugging Note

If you read this far than you probably know how important debugging is, but I sometimes like to stick the best tips deep in my articles to make sure only YOU find it. GRTFM isn't used on this site, it's mostly a requirement because my writing can get pretty bad.. The point, debugging is more than a crucial requirement if you want to do anything cool. Don't worry I got you.. check my AskApache Debug Viewer Plugin from the official WP site. It's pretty close to providing as verbose amount of information that I could possibly figure out how to get out of php, probably more than you have ever seen at least, I focused on quantity. I use it all the time on new installs as there is no setup required and it tells me advanced information about the setup of the server, hacker code for sure.

Here's a quick function to see set global vars, I just think this is interesting code.

function askapache_global_debug(){
  global $_GET,$_POST,$_COOKIE,$_SESSION,$_ENV,$_FILES,$_SERVER,$_REQUEST,$HTTP_POST_FILES,$HTTP_POST_VARS,$HTTP_SERVER_VARS,$HTTP_RAW_POST_DATA,$HTTP_GET_VARS,$HTTP_COOKIE_VARS,$HTTP_ENV_VARS;
  $gv=create_function('$n','global $$n; ob_start(); if ( is_array($$n) && sizeof($$n)>0 && print("[{$n}]\n") ) print_r($$n);return ob_get_clean();');
  foreach (array('_GET','_POST','_COOKIE','_SESSION','_ENV','_FILES','_SERVER','_REQUEST','HTTP_POST_FILES','HTTP_POST_VARS','HTTP_SERVER_VARS','HTTP_RAW_POST_DATA','HTTP_GET_VARS','HTTP_COOKIE_VARS','HTTP_ENV_VARS') as $k)echo $gv($k);
  print_r(get_defined_constants());
}

Crazy Advanced Mod_Rewrite Debug Tutorial

AskApache — Fri, 11 Sep 2009 17:55:32 +0000

AskApache.com

Are you an advanced mod_rewrite expert or guru? This article is for YOU too! Just make sure to read all the way to the bottom..

The following undocumented techniques and methods will allow you to utilize mod_rewrite at an "expert level" by showing you how to unlock its secrets.

Most if not all web developers and server administrators struggle with Apache mod_rewrite. It's very tough and only gets a little easier with practice. Until Now! Get ready to explode your learning curve, I figured something out.

Why mod_rewrite is so tough

I have come to the conclusion, after many hours of zenful thought, that the reason mod_rewrite is so tough is pretty obvious, people are trying to apply regular-expressions to URLs and Variables that they don't really understand. They understand what they want, but they don't understand what the URLS and Variables are that they are trying to rewrite.

Hit-Or-Miss with mod_rewrite

A lot of the mod_rewrite "experts" and "gurus" floating around the net absolutely know their mod_rewrite, but what separates them from a beginner or novice is for the most part an understanding of what the URLS and Variables look like that are targeted by the regular expressions. Take this simple rewriterule that rewrites requests made without the www to www.

RewriteEngine On
RewriteBase /
 
RewriteCond %{HTTP_HOST} !^www\.askapache\.com$ [NC]
RewriteRule .+ http://www.askapache.com%{REQUEST_URI}

Pretty simple right? WRONG. Most people could not figure that out..

Why?

The reason intelligent people can't figure that out is because they have no idea what HTTP_HOST or REQUEST_URI actually looks like. How can you write a rule for something if you don't know what it looks like? You can't.

When Not To Use Mod_Rewrite

Ok so heres an important concept that alot of people haven't heard. You should only use mod_rewrite's rewriterule when you use a rewritecond or if you are rewriting internally like my feedcount hack.

If you are simply redirecting one url to another, you should definately be using the much easier mod_alias's redirect and redirectmatch, which is enabled on most Apache servers.

When To Use Mod_Rewrite

So then, you should only use mod_rewrite's rewriterule when you are checking against one of the Apache Environment Variables to determine whether to rewrite or not. This is where the Apache Documentation is grossly lacking. They don't tell you what those variables look like, leaving us completely incapable of creating rewrites based on them. Not anymore.

Mod_Rewrite Environment Variables (The Secret)

Here's the variables I have found accessible by mod_rewrite (both documented and undocumented). A thing to note is that you can set these variables early in an .htaccess file using SetEnv, RewriteRule, Header, etc.. and they will be accessible at the end of the .htaccess file.

Decoding Mod_Rewrite Variables

So when I realized my problem was that I didn't know the value of the variable being tested by the RewriteCond, I set out to try and discover how to view those variables.. Keep in mind you can also use RewriteLogging, but its only allowed for root users who can edit the httpd.conf, this is .htaccess.

Setting Environment Variables with RewriteRule

I discovered a multitude of methods to set and view apache environment variables, using various modules and some core tricks, but the method that allows me to view the most environment variables is RewriteRule.. I wanted to use SetEnvIf more, but its just not as powerful as mod_rewrite, due to programming.

This code sets the variable INFO_REQUEST_URI to have the value of REQUEST_URI.

RewriteEngine On
RewriteBase /
RewriteRule .* - [E=INFO_REQUEST_URI:%{REQUEST_URI},NE]

Saving the Apache Variable Values

Now the trick is how to view that environment variable... The method I came up with is nice... We will send the environment variable value in an HTTP Header, as there isn't much data manipulation/validation so you get an accurate look at the actual value.. At first I tried adding the variable value to a redirection using the query_string.. but a HTTP_USER_AGENT value doesn't play well as a query_string.

Using RequestHeader in .htaccess

This code takes advantage of the incredible mod_headers apache module to actually ADD a whole new header to YOUR request. Seriously one of the coolest tricks I've found yet.. Its almost the same as being able to spoof POST requests! Since Headers can be protected data... especially the HTTP_COOKIE header..

RequestHeader set INFO_REQUEST_URI "%{INFO_REQUEST_URI}e"

Viewing the Variable Values

Now you can use any kind of server-run interpreter like perl, php, ruby, etc., to view all the variable values. All cgi-script handlers like those are able to view request headers..

PHP Code to access Apache Variables

Works even in safe-mode... any interpreter can view HTTP Headers! Note that each of these variables are added as HTTP headers to the request for the script.. kinda confusing.. So each variable sent as a header is prefixed with HTTP_ to denote it was a header.

$r)
{
  if(substr($v,0,9)=='HTTP_INFO')
  {
    if(!empty($r))$INFO[substr($v,10)]=$r;
    else $MISS[substr($v,10)]=$r;
  }
}
 
/* thanks Mike! */
ksort($INFO);
ksort($MISS);
ksort($_SERVER);
 
echo "Received These Variables:\n";
print_r($INFO);
 
echo "Missed These Variables:\n";
print_r($MISS);
 
echo "ALL Variables:\n";
print_r($_SERVER);
?>

Time to Get Crazy

Just create the above php file on your site as /test/index.php or whatever, then create /test/.htaccess which should contain the below .htaccess file snippet. Now just request /test/index.php and be amazed! If you're looking for more general help check out this excellent mod_rewrite cheat sheet.

Ok, so I've prepared the .htaccess code you can use to view the values of all these variables. Just add it to a .htaccess file and make a request. For this test I created an index.php file that printed out all the $_SERVER variables, and made requests to it.

Emulating ErrorDocuments with Mod_Rewrite

The ErrorDocument directive is helpful because an errordocument is called differently then a normal file, and it contains special variables to help an admin debug.

I've wanted to use a RewriteCond + a RewriteRule to cause an Apache ErrorDocument to be displayed for a long time... I finally figured it out. Simply use the HTTP STATUS CODE trick in combination with a simple RewriteRule to trigger an Apache ErrorDocument.

This code emulates the internal 404 process Apache goes through.. If the file is not found it requests the /test/trigger-error/404 internally which triggers the 404 ErrorDocument.

ErrorDocument 404 /test/errordocument/404.html
Redirect 404 /test/trigger-error/404
 
RewriteEngine On
RewriteBase /
RewriteCond %{ENV:REDIRECT_STATUS} !=404
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* /test/trigger-error/404 [L]

Big Deal.. you might say... well consider that this works with any status code, and using this method you now have the power to trigger any errordocument page based on any kind of rewritecond. I'll be writing about some practical uses for this powerful method in the coming weeks, but heres a good example now so you can see how it can be used.

This bit of code Triggers the 505 HTTP Version Not Supported When a request is made to the server with a protocol other than 1.1.

ErrorDocument 505 /test/errordocument/505.html
Redirect 505 /test/trigger-error/505
 
RewriteEngine On
RewriteBase /
 
RewriteCond %{ENV:REDIRECT_STATUS} !=505
RewriteCond %{THE_REQUEST} !^[A-Z]{3,9}\ /.*\ HTTP/(0\.9|1\.0|1\.1) [NC]
RewriteRule .* /test/trigger-error/505 [L]

YES! I realize I didn't explain that very well, I didn't realize it was that complicated.. I wanted to go into how to use these advanced tricks and methods to achieve some really cool stuff, but explaining just this little bit took me awhile and I'm out of page space!

So play around with this and I'll post back some of the untapped sicknesses you can give a website with such powerful methods at your disposal.

THE Ultimate Htaccess

AskApache — Sat, 10 Jan 2009 13:05:32 +0000

AskApache.com

.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.

This 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. Information is freedom, and freedom is information, so this blog has the least restrictive copyright for you. Feel free to modify, copy, republish, sell, or use anything on this site ;)

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 sections in access.conf, or from defaults in srm.conf, which actually behaves for most purposes almost exactly like ).

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

Htaccess 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.

In 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.

httpd-multilang-errordoc.conf: The configuration below implements multi-language error documents through content-negotiation

# AddIcon* directives tell the server which icon to show for different files or filename extensions.
AddIconByEncoding (CMP, /icons/compressed.gif) x-compress x-gzip
AddIconByType (TXT, /icons/text.gif) text/*
AddIcon /icons/folder.gif ^^DIRECTORY^^
# DefaultIcon is which icon to show for files which do not have an icon explicitly set.
DefaultIcon /icons/unknown.gif
# AddDescription allows you to place a short description after a file in server-generated indexes.
AddDescription "GZIP compressed document" .gz
# ReadmeName is the name of the README file the server will look for by default, and append to directory listings.
ReadmeName README.html
# HeaderName is the name of a file which should be prepended to directory indexes.
HeaderName HEADER.html

Here are the rest of them if you wanna take a look. (httpd-mpm.conf, httpd-default.conf, httpd-ssl.conf, httpd-info.conf, httpd-vhosts.conf, httpd-dav.conf)

PHP htaccess tips

By using some cool .htaccess tricks we can control PHP to be run as a cgi or a module. If php is run as a cgi then we need to compile it ourselves or use .htaccess to force php to use a local php.ini file. If it is running as a module then we can use various directives supplied by that modules in .htaccess

HTTP to HTTPS Redirects with mod_rewrite

This 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.

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 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):
