Pretty Permalinks for WordPress in IIS6


// This is the default file for the site. Usually index.php

$default = ‘index.php’;

// The name of this file.

// Set this value for the URL in Custom Error Properties of your website in IIS.

// Goto: IIS Manager > Websites > [Site Name] > Properties > Custom Errors >

// 404 & 404;2 & 404;3 > URL (Requires a ‘/’ prefix in IIS).

$thisfile = ‘404-handler.php’;

$_SERVER[‘ORIG_PATH_TRANSLATED’] = str_replace($thisfile, $default, $_SERVER[‘ORIG_PATH_TRANSLATED’]);

$_SERVER[‘SCRIPT_FILENAME’] = str_replace($thisfile, $default, $_SERVER[‘SCRIPT_FILENAME’]);

$_SERVER[‘ORIG_PATH_INFO’] = str_replace($thisfile, $default, $_SERVER[‘ORIG_PATH_INFO’]);

$_SERVER[‘SCRIPT_NAME’] = str_replace($thisfile, $default, $_SERVER[‘SCRIPT_NAME’]);

$_SERVER[‘PHP_SELF’] = str_replace($thisfile, $default, $_SERVER[‘PHP_SELF’]);

$_SERVER[‘PATH_INFO’] = false;



$pos = strrpos($qs, ‘://’);

$pos = strpos($qs, ‘/’, $pos + 4);

$_SERVER[‘URL’] = $ru = substr($qs, $pos);

$qs = trim(stristr($ru, ‘?’), ‘?’);

// Required for WordPress 2.8+


// Fix GET vars

foreach ( $_GET as $var => $val ) {

if ( substr($var, 0, 3) == ‘404’) {

if ( strstr($var, “?”) ) {

$newvar = substr($var, strpos($var, ‘?’) + 1);

$_GET[$newvar] = $val;








Originally From :

Create a 404 page and put the following 4 lines in it:

$_SERVER['REQUEST_URI'] = substr($qs, strpos($qs, ':80')+3);

All this does is fix the REQUEST_URI and PATH_INFO variables and then include index.php, so WordPress will do the rest. It’s simple, it doesn’t duplicate functionality already in WordPress and it doesn’t have the overhead of another http request for every page hit. The installation steps are:

  1. Create the file wp-404-handler.php in your base WordPress folder.
  2. Set your sites 404 page to point to the wp-404-handler.php url. Most control panels at web hosts allow you to do this. If you’ve got the option to select between FILE and URL then choose URL.
  3. Go to Options -> Permalinks in your WordPress admin page, and choose an appropriate structure for your links. I chose Custom with this pattern:
  4. Enjoy!
