Here are some specific htaccess examples taken mostly from my WordPress Password Protection plugin, which does alot more than password protection as you will see from the following mod_rewrite examples. These are a few of the mod_rewrite uses that BlogSecurity declared pushed the boundaries of Mod_Rewrite! Some of these snippets are quite exotic and unlike anything you may have seen before, also only for those who understand them as they can kill a website pretty quick.

Map all URIs except those corresponding to existing files to a handler

RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-d
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-f
RewriteRule . /script.php

Map any request to a handler

In the case where all URIs should be sent to the same place (including potentially requests for static content) the method to use depends on the type of the handler. For php scripts, use: For other handlers such as php scripts, use:

RewriteEngine On
RewriteCond %{REQUEST_URI} !=/script.php
RewriteRule .* /script.php

And for CGI scripts:

ScriptAliasMatch .* /var/www/script.cgi

Map URIs corresponding to existing files to a handler instead

RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d [OR]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f
RewriteCond %{REQUEST_URI} !=/script.php
RewriteRule .* /script.php

If the existing files you wish to have handled by your script have a common set of file extensions distinct from that of the hander, you can bypass mod_rewrite and use instead mod_actions. Let's say you want all .html and .tpl files to be dealt with by your script:

Action foo-action /script.php
AddHandler foo-action html tpl

Deny access if var=val contains the string foo.

RewriteCond %{QUERY_STRING} foo
RewriteRule ^/url - [F]

Removing the Query String

RewriteRule ^/url /url?

Adding to the Query String

Keep the existing query string using the Query String Append flag, but add var=val to the end.

RewriteRule ^/url /url?var=val [QSA]

Rewriting For Certain Query Strings

Rewrite URLs like http://askapache.com/url1?var=val to http://askapache.com/url2?var=val but don't rewrite if val isn't present.

RewriteCond %{QUERY_STRING} val
RewriteRule ^/url1 /url2

Modifying the Query String

Change any single instance of val in the query string to other_val when accessing /path. Note that %1 and %2 are back-references to the matched part of the regular expression in the previous RewriteCond.

RewriteCond %{QUERY_STRING} ^(.*)val(.*)$
RewriteRule /path /path?%1other_val%2

Mod_Rewrite Security originally appeared on AskApache.com

WARNING! This is for advanced users of the shell, this is NOT a howto or tutorial. The thing is, I googled how to uninstall cpanel and for once in my life I came up empty.. And certainly the cpanel official sites themselves don't provide any instructions other than to say "Dont uninstall it, reinstall your entire operating system without it.".. they sure don't seem confident that they know exactly what their code is doing. Cpanel is great for most people, perfect for many situations, so don't get me wrong.. this is just for fun.

Why Uninstall?

Why? Because I have always built my servers, php installations, perl installs, ruby, iptables, everything from source. I read the INSTALL/README docs, I read the man pages, and I read the info pages as well. I google for configuration advice, I google for tips, and I don't need a web-based perl script messing my stuff up!

The main problems I had with cpanel, which really is a great bit of software for millions of website developers, is that it was incredibly sneaky! I used it for about 6 months and spent that entire time trying to figure out what the heck it was doing. A couple issues that I really disliked, it takes over your bind install, it takes over your apache install, it takes over your php install. And although it does let you configure some things (very few) for custom configurations and the like, I just don't need any of that. By removing the darn thing I am saving GIGS of space on my server, tons of bandwidth, and most importantly to me I am saving CPU and processing time along with RAM and IO speed.

Anything Else

Please.. I could go on for DAYS! Another reason I have wanted to be rid of cpanel is that I like my servers to be as lean and mean as possible. This means I like as few files and processes as possible. There are many benefits to this, like it's much easier for my integrity checking software and rootkit/antivirus software to run and drastically reduces the false positives. And there is that glaring security issue of constantly having cpanel run it's own software to create the WHM/Cpanel web interface, which is accessible online. I haven't researched cpanel security at all, it's possible that it never has security problems that are published, but for me, why take the chance?

Warning - Caution!

The following is just a quick reference of some of the commands I used to uninstall cpanel. This is for advanced users of the shell. If you aren't that advanced and you run a single one of these commands without fully understanding it, you will probably kill your server, probably lose everything on it permanently, probably not have a website or email for weeks.. So backup all your data FIRST. Also, if you aren't 100% sure you won't run into problems, you should contact your hosts technical support - but be prepared for some MAJOR negativity.. cpanel makes things very easy for hosts, and the last thing tech support wants is to fix a server broken by someone who doesn't know what they are doing.

Last Warning!

Unless you understand what theses commands do and the purpose they serve, do not try any of this. These are not the exact commands I used verbatim, they are also not in order. I only put them up here because I was so amazed that google didn't have any uninstall cpanel intructions. Hopefully it's not a conspiracy that will get my site taken down.. ;)

That said and out of the way, it really only took me about 10 minutes to uninstall cpanel completely. But keep in mind I have been closely monitoring and debugging cpanel for 6 months, so I knew what I was doing. And finally, I do apologize for not having better instructions.. but hey, if you don't get this then you have no business trying to figure out how to uninstall cpanel! It's great software and shouldn't be removed unless you are fully capable of managing email/dns/www/ftp and any/all other servers and services on your machine by hand.

Do This First

I have a few drafts I'm working on at the moment with specifics, but for now you will have to figure it out with google. Basically you want to make sure you don't totally knock your machine offline without being able to reconnect. What I do is compile a static version of openssh and a few other security-type shell tools, and configure this binary sshd to run by using inittab, which is the file run by init (pid 1) and makes sure if it dies it is restarted. Here is my /etc/inittab to run the static sshd binary:

hh:12345:respawn:/failover/os/sbin/aassh -D -q -u0 -f /failover/os/etc/aassh

Another trick is to keep a detached screen logged in to root. That way if you mess up your sudoers or securetty or pam or whatever, you can just reattach and fix it.

Finally, you may want to setup your syslog to start earlier than usual, and set up more than normal verbosity. ( I take it to the max ). Then you should setup a 2nd server or machine somewhere to act as a syslog server. Lastly, configure your web server syslog to copy all messages to the remote syslog you set up. I use a reverse ssh tunnel to encrypt the syslog packets, but when I do something serious like reboot after uninstalling cpanel, I prepare for it by adding additional networking routes on my machine to make sure I will get some logs even if sshd cant start or even if my network addresses aren't brought up correctly.

If that sounds easy to you, please continue. If you are saying: Wha??? Continue in read-only mode.

Also, you can't just uninstall cpanel, I have replaced a lot of cpanel already, like building my own bind, apache, php, syslog and making sure they work and aren't being tampered with by cpanel. Basically cpanel runs everything on your server in most cases, so you should prepare by creating your own static software to replace cpanel, and make sure it works.

Find files Accessing /var/cpanel

More than likely these will need to be killed.

lsof +w -Rg -nP +c15 -x f +D /var/cpanel
lsof +w -Rg -nP +c15 -x f +D /usr/local/cpanel

Killing cpanel

Just an example, your machine may have a lot more than these, I have been slowly taking control of my machine back from cpanel for 6 months, so it was easier for me.

for P in tailwatchd queueprocd cpanellogd exim; do pkill -9 $P; done

alias NA='nice find $PWD -mount -depth'
alias NAF='nice find $PWD -mount -depth | xargs -IF87 file F87'

Watch out for crontab

An example of the sneakiness (from my POV, from most it's called builtin robustness) that cpanel does is automagically adding crontab entries that make it behave similarly to a self-propagating virus. If you don't disable the cronjobs and kill the right processes within a short period of time, be prepared for a magic resurrection.

Here's my awesome crontab information function, you will need to check every file, it lists the default crons on my box, and every users crontab, but it can't account for other cron software like at and other crons.

function askapache_crontab()
{
  local GG i;
  for i in `getent passwd|cut -d ":" -f1`;
  do
    GG=$(sudo crontab -u $i -l 2>$N6 | tr -s '\n\000' | sed '/^#/d');
    [[ ${#GG} -gt 3 ]] && sleep 1 && echo -e "$i \n\n${GG}"
  done;
   sleep 4;
   ls -aLls1ch --color=always /etc/cron.{hourly,daily,weekly,monthly,d} | sed '/^total/d; /\ drwxr-xr-x/d';
}

Find INIT scripts with cpanel

This is the main startup script: /usr/local/cpanel/etc/init/startup

I had no idea ruby-on-rails was being controlled by cpanel.. sneaky bugger. You can tell by all of these advanced unix commands just how difficult it would be to uninstall cpanel, its totally like the Alien!

Turn off cpanel services

You should remove the below delete command and start by just disabling the inits by turning them off. Then reboot. Then delete. If your machine won't reboot, I told you so, Cpanel told you so, and likely your host told you so.

for S in cpanel ror securetmp fastmail exim; do R=$(command chkconfig --level 123456 $S off ||echo); R=$(command chkconfig --del $S ||echo); done

HTTPD

If you are running chrooted httpd then you'll need to make sure you don't delete your entire webserver on accident. Here's a relevant part from the /etc/init.d/httpd script.

# the path to your httpd binary, including options if necessary
if [ -e "/etc/chroothttpd" ]; then
        HTTPD=/usr/local/cpanel/bin/chroothttpd
else
        HTTPD=/usr/local/apache/bin/httpd
fi

Finding files owned by cpanel

Some super cool bash commands in this post.. let's start with one to find all the files and folders on your machine owned by cpanel. Check your /etc/passwd file for your machines specific usernames and groups. This command saves all the filenames to ~/cpanel-files-backup.txt, which is used by tar next to create a backup of all of them.

{ find / -mount -depth -maxdepth 150 \( -group cpanel -o   -group cpanel-phpmyadmin -o -group cpanel-phppgadmin   -o -group cpanelphpmyadmin   -o -group cpanelphppgadmin   -o -group cpanelhorde   -o -group cpanelroundcube \) -print; find / -mount -depth -maxdepth 150 \( -user cpanel -o   -user cpanel-phpmyadmin -o -user cpanel-phppgadmin   -o -user cpanelphpmyadmin   -o -user cpanelphppgadmin   -o -user cpanelhorde   -o -user cpanelroundcube \) -print; } > ~/cpanel-files-backup.txt

Here's another way to search directories.

 grep --color=always -Hir cpanel /var

Create the Backup

Note that you must have the latest version of tar for this exact command, also you should backup /var/cpanel and /usr/local/cpanel and /etc and heck the whole machine why dontcha!

tar -T ~/cpanel-files-backup.txt -cvz --checkpoint=1000 --checkpoint-action="ttyout=\rHit %s checkpoint #%u" -f /cpanel-files-backup.tgz --totals

Remove Files

Once you do this your upstream without a paddle, you better make sure you know what you're doing with this. This removes all those files.

cat ~/cpanel-files-backup.txt | xargs -I'F87' rm -vfr F87

Additionally you will want to remove /usr/local/cpanel and /var/cpanel - What I always do when running as root is alias my rm command to instead simply move the files to a .trash folder. That way if something goes bork you have a better chance at fixing it.

Find Group-Owned Files

find / -mount -depth -maxdepth 150 \
\(  -group cpanel -o \
  -group cpanel-phpmyadmin \
  -o -group cpanel-phppgadmin \
  -o -group cpanelphpmyadmin \

Reinstall CSF

The only thing I actually used that came with cpanel is the CSF/LFD Firewall package, which is a fantastic piece of software. I had to reinstall this, and to get it working without cpanel add the following line to the csf.conf

GENERIC = "1"

Thats It

Now once you've cleaned up everything, you should try everything conceivable to get an error before rebooting. Like you should start and stop every service in /etc/init.d/, you should use telinit to check various runlevels (which keeps your sshd connection still live). Go all out, should take at least a full hour.

Another thing I like to do is rebuild alot of my source-built software again in case anything got messed up. I upgrade perl from cpanels 5.8.8 to 5.10, which is pretty thorough, and you know, reinstall anything else I think I might need. One of the benefits of compiling your own software is all I have to do is cd to the source directory and type make -B && ( { make test || make check || make checks || make tests; } || echo ) && sudo make install and that's it. The tests/checks are optional of course.

If anyone actually ever reads this and does it, please share your advice here.. everybody knows we need it! Good Luck

HOWTO: Uninstall CPANEL over SSH originally appeared on AskApache.com

Here's an example of validation links from the AskApache footer.

RSS | XHTML 1.1 | CSS 2.1

document.getElementById("validat").innerHTML += ' | <a href="http://feedvalidator.org/check.cgi?url=http://www.askapache.com/feed/">RSS</a>  | <a href="http://validator.w3.org/check/referer?ss=1;outline=1;sp=1;debug">XHTML 1.1</a> | <a href="http://jigsaw.w3.org/css-validator/check/referer?warning=0">CSS 2.1</a>';

Main Javascript Object

Now here's the object that contains all the functions and variables. This is smart to do as a function (all javascript really) because it makes it much safer as it won't conflict with other scripts or having naming collisions. And portable code is always something to strive for.

var AskApacheJS = new Object({
 
  /* Runs on page load.  Initializes ajs as being an alias for AskApacheJS,
  * and runs the append_validation_links function after 5 seconds. */
  _init: function () {
    /*console.log('Running _init');*/
    window.ajs = this;
    setTimeout(ajs.append_validation_links, 5000);
  },
 
  append_validation_links: function () {
    var ac=ajs.gi('validatelinks');
 
    if(ac) {
      var url=encodeURI(window.location).toString().replace(/&/g,"&");
 
      ac.innerHTML =
        "<a href=\"http://jigsaw.w3.org/css-validator/check/referer?warning=0&amp;profile=css21&amp;warning=1\"></a> | "
      + "<a href=\"http://validator.w3.org/feed/check.cgi?url="+url+"\"></a> | "
      + "<a href=\"http://validator.w3.org/check/referer?ss=1;outline=1;sp=1;debug\"></a> | "
      + "<a href=\"http://validator.w3.org/checklink?check=Check&amp;hide_type=all&amp;summary=on&amp;uri="+url+"\"></a> | "
      + "<a href=\"http://www.cynthiasays.com/mynewtester/cynthia.exe?rptmode=-1&amp;url1="+url+"\"></a> | "
      + "<a href=\"http://www.cynthiasays.com/mynewtester/cynthia.exe?rptmode=2&amp;url1="+url+"\"></a>";
    }
  },
 
  /* gi stands for get item, and returns an element by id. Very robust: if it cant find the object it logs to the console. */
  gi: function (B) {
    /*console.log('Running gi '+B);*/
    try {var b = document.getElementById(B);}
    catch(e1) {b = null;try {b = document.all(B);}
    catch(e2) {b = null;try {b = document.layers[B];}
    catch(e3) {b = null;}}}
    return (ajs.isobj(b)) ? b : ajs.er("ERR gi " + B);
  },
 
  /* This function writes the passed msg to the console as type 'error'
  *  and then returns false since it was afterall an error. */
  er: function (msg) { console.error(msg); return false; },
 
  /* Returns true or false based on whether the passed item was an object, used by gi. */
  isobj: function (_1e) { return (typeof _1e != "undefined" && typeof _1e === "object") ? true : false;  }
});

Initialize the Object

;(function () {
  if (!window.ajs)var ajs=AskApacheJS;window.ajs=ajs=AskApacheJS;
  try{ajs._init();}catch(e){AskApacheJS._init();}
})();

FireBug Logging

First things first, this sets up all the logging and debugging needed. This lets you control debugging output displayed in the console used by debuggers like FireBug. Add this to the very top of your javascript.

if(!this["console"]){this.console = {};}
var i=0,tn,cn=["assert","count","debug","dir","dirxml","error","group","groupEnd","info",
"profile","profileEnd","time","timeEnd","trace","warn","log"];
while ((tn = cn[i++])) {
  if (!console[tn]) {
    (function () { var a = tn + "", console[a] = ("log" in console) ?
    function(){var a=tn+"";console[a]=("log" in console) ?
    function(){var b=Array.apply({},arguments);b.unshift(a+":");
    console["log"](b.join(" "))} : function(){}})()
  }
};

Turning On/Off Debugging

It's useful to quickly be able to switch between having the console logging turned on or off. The downside to keeping it on of course is overhead. Here's a very simple method that I use, advanced users use more sophisticated methods than this. Here are the regexes (Adobe CS4 DreamWeaver).

# To turn console logging on
Search for: /\*console.log([^;]*);\*/
Replace with: console.log$1;
 
# To turn console logging off
console.log([^;]*);
/*console.log$1;*/

Console Logging Commented Out

Here's an example of howto log the isobj function from the above object. isobj: function (_1e) { /*@console@*console.log('Running isobj ');**@console@*/ return (typeof _1e != ajs.undefined && typeof _1e === "object") ? true : false; },

Quick and Easy Example

  document.getElementById('validatelinks') && document.getElementById('validatelinks').innerHTML =
        "<a href=\"http://jigsaw.w3.org/css-validator/check/referer?warning=0&amp;profile=css21&amp;warning=1\"></a> | "
      + "<a href=\"http://validator.w3.org/feed/check.cgi?url="+url+"\"></a> | "
      + "<a href=\"http://validator.w3.org/check/referer?ss=1;outline=1;sp=1;debug\"></a> | "
      + "<a href=\"http://validator.w3.org/checklink?check=Check&amp;hide_type=all&amp;summary=on&amp;uri="+url+"\"></a> | "
      + "<a href=\"http://www.cynthiasays.com/mynewtester/cynthia.exe?rptmode=-1&amp;url1="+url+"\"></a> | "

Javascript Snippet to Add HTML, CSS, and FEED Validation Links originally appeared on 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.

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

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.

Redirect 100 /e/100
Redirect 101 /e/101

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.

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 Codes and Htaccess ErrorDocuments originally appeared on AskApache.com

The php part of this article is based on my Advanced WordPress 404.php article from 2008. Many of the following ideas came out of the research performed to enumerate every single Apache ErrorDocument, including learning how to view the defaults and many cool tricks for htaccess.

The PHP HTTP ErrorDocument Handler

Just save this as /err.php or whatever. The best is to put it in a cgi-bin script-alias directory under your DOCUMENT_ROOT like /cgi-bin/e.php but most people don't know how. That way you can setup some advanced stuff in a /cgi-bin/.htaccess file. If you are interested in locking it down, I recommend reading Securing php.ini and php-cgi with .htaccess.

Advantages and Reasons for Using

Fast, HTTP Protocol Compliance, protection. If you are reading this article, you already know and just want to check out the code!

Htaccess ErrorDocument Tips

The thing is, how do you setup your website to use this php file to be able to handle all those HTTP Status Codes gracefully? You just need to configure your server to use that php file for any Status Codes you want. If you are building an ErrorDocument handling system for a server-wide, multi-site, setup, you will want to instead use the method I use. Instead of using a separate language like PHP, Python, Ruby, Perl, etc, to handle errors, I rely on the very safe and fast SSI method. I detailed the advanced ErrorDocument SSI (.htaccess or httpd.conf)..

If you instead like most of us, you will be setting this up for 1 site, or 1 DOCUMENT_ROOT serving virtual hosts. For that the best method is to modify your .htaccess file.

Using Redirect in .htaccess to trigger Errors

This is one of my all time favorite discoveries from my apache studies. It's documented elsewhere on this site, but if you want to test it out, just request www.askapache.com/show-error-402. Of course the error handling that I have in place is quite nice.

Redirect 400 /show-error-400
Redirect 401 /show-error-401
Redirect 402 /show-error-402
Redirect 403 /show-error-403
Redirect 405 /show-error-405
Redirect 406 /show-error-406
Redirect 407 /show-error-407
Redirect 408 /show-error-408
Redirect 409 /show-error-409
Redirect 410 /show-error-410
Redirect 411 /show-error-411
Redirect 412 /show-error-412
Redirect 413 /show-error-413
Redirect 414 /show-error-414
Redirect 415 /show-error-415
Redirect 416 /show-error-416
Redirect 417 /show-error-417
Redirect 418 /show-error-418
Redirect 419 /show-error-419
Redirect 420 /show-error-420
Redirect 421 /show-error-421
Redirect 422 /show-error-422
Redirect 423 /show-error-423
Redirect 424 /show-error-424
Redirect 425 /show-error-425
Redirect 426 /show-error-426
Redirect 500 /show-error-500
Redirect 501 /show-error-501
Redirect 502 /show-error-502
Redirect 503 /show-error-503
Redirect 504 /show-error-504
Redirect 505 /show-error-505
Redirect 506 /show-error-506
Redirect 507 /show-error-507
Redirect 508 /show-error-508
Redirect 509 /show-error-509
Redirect 510 /show-error-510

Powerful Mod_Rewrite Trick

Here's how to combine the power of mod_rewrites ability to parse requests and environment variables with the above Redirect trick to trigger a specific ErrorDocument based on the query_string parameter error. This trick is only on AskApache.com, very powerful trick if you need to force ErrorDocuments.

RewriteCond %{QUERY_STRING} error=([4|5][0-9][0-9]) [NC]
RewriteCond %{QUERY_STRING} !404
RewriteRule . /show-error-%1 [L]

ErrorDocument Example for .htaccess

So if you save the php file as err.php in your DOCUMENT_ROOT, these are the htaccess commands that will enable its use.

The addition of the ?error=num should be unneccessary on a good linux machine, it's a way for lesser OS's and webhosts to still be able to use errordocuments. Basically Apache handles ErrorDocuments by setting special DEBUGGING variables (Start with REDIRECT_) so it's very easy to determine the STATUS CODE by just viewing $_SERVER['REDIRECT_STATUS']. If a recursive type of redirect is going on, you may see $_SERVER['REDIRECT_REDIRECT_STATUS']. Dumb (consistently) OS's like a Windows server almost always have problems with things like that, because they don't give a hoot about POSIX or standards, why should they when no one can view their code anyway. Here are some more details on the REDIRECT_STATUS and other ways to use these variables.

If you want to learn how to enumerate and view the different variables that are in your Apache environment, I think I have the best tutorial on the planet for how to do this with PHP and mod_rewrite with mod_headers. That article is the basis for anyone who is hired to do mod_rewrites on a new server without root access. I would say that one article will inform you more about mod_rewrite then any other article on this site.

###
# ErrorDocument: In the event of a problem or error, what the server will return to the client. URLs
# can begin with a / for local web-paths (relative to DocumentRoot), or be a full URL which the client
# can resolve. Alternatively, a message can be displayed.  If a malformed request is detected, normal
# request processing will be immediately halted and the internal error message returned.
#
# Prior to version 2.0, messages were indicated by prefixing them with a
# single unmatched double quote character.
#
# The special value default can be used to specify Apache's simple hardcoded message and
# will restore Apache's simple hardcoded message.

PHP to handle HTTP Status Codes for ErrorDocument originally appeared on AskApache.com

Here is even more information from the Ultimate Htaccess Part I. For now this is very rough and you will want to come back later to read it.

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>
D
</Files>
<VirtualHost *>
<Directory /a/b>
B
</Directory>
</VirtualHost>
<DirectoryMatch "^.*b$">
C
</DirectoryMatch>
<Directory /a/b>
A
</Directory>

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):

Ultimate Htaccess Part II originally appeared on 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
#
# 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 'application/rdf+xml; charset=UTF-8' .rdf
AddType 'application/xhtml+xml; charset=UTF-8' .xhtml
AddType 'application/xhtml+xml; charset=UTF-8' .xhtml.gz

AddType text/plain .ini .sh .bsh .bash .awk .nawk .gawk .csh .var .c .in .h .asc .md5 .sha .sha1
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.

DefaultType text/html

# 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]

### 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.

# viewed by Web clients.
#

</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

# 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.

# AddEncoding allows you to have certain browsers uncompress

# 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
 
#
# 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 php-cgi .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 php-cgi /cgi-bin/php.cgi
