Enabling Search Engine Friendly (SEF) URLs on IIS

From Joomla! Documentation

Helicon ISAPI Rewrite 3 located at http://www.helicontech.com/isapi_rewrite/ now provides near identical mod_rewrite functionality.

IIS 7 has its own rewrite module now, the URL Rewrite which works excellent and doesn't require third party installs. It can be enabled through the Web Platform Installer. In the Joomla config turn on both the SEF and Apache mod_rewrite, next create a rule under IIS URL Rewrite: Pattern field: ^([^/]+)/?$ Ignore case ON Action type: Rewrite Rewrite URL: index.php/


The default rewrite rules can be used and the following code inserted to the top of the index.php file:

if (isset($_SERVER['HTTP_X_REWRITE_URL']))
{
    $_SERVER['REQUEST_URI'] = $_SERVER['HTTP_X_REWRITE_URL'];
}



First job is to install ISAPI rewriter of your choice http://www.isapirewrite.com/ or http://cheeso.members.winisp.net/IIRF.aspx

ISAPI ReWrite has a lite version (limited) and IIRF (IonicIsapiRewriter) is freeware always updated and the source is free!

Both are configured via file IsapiRewrite4.ini (you dont need to worry about .htaccess.txt ignore it).

The following entries for ISAPI REWRITE:

RewriteLog  D:\temp\iirfLog.out
RewriteLogLevel 3
 
IterationLimit 10
 
# Joomla/Mambo rewrite rules
RewriteRule  ^/$                      /index.php
RewriteRule ^/content/blogsection/([^/]+)/([^/]+)/ /index.php?option=com_content&task=blogsection&id=$1&Itemid=$2
RewriteRule ^/content/blogcategory/([^/]+)/([^/]+)/ /index.php?option=com_content&task=blogcategory&id=$1&Itemid=$2
RewriteRule ^/content/section/([^/]+)/([^/]+)/ /index.php?option=com_content&task=section&id=$1&Itemid=$2
RewriteRule ^/component/option,([^/]+)/([^/]+),([^/]+)/([^/]+),([^/]+)/([^/]+),([^/]+) /index.php?option=$1&$2=$3&$4=$5&$6=$7
RewriteRule ^/component/option,([^/]+)/([^/]+),([^/]+)/([^/]+),([^/]+) /index.php?option=$1&$2=$3&$4=$5
RewriteRule ^/component/option,([^/]+)/([^/]+),([^/]+)/ /index.php?option=$1&$2=$3
RewriteRule ^/content/category/([^/]+)/([^/]+)/([^/]+)/ /index.php?option=com_content&task=category&sectionid=$1=&id=$2&Itemid=$3
RewriteRule ^/content/view/([^/]+)/([^/]+)/([^/]+)/([^/]+)/ /index.php?option=com_content&task=view&id=$1&Itemid=$2&limit=$3&limitstart=$4
RewriteRule ^/content/view/([^/]+)/([^/]+)/ /index.php?option=com_content&task=view&id=$1&Itemid=$2

The following is for IonicIsapiRewriter:

IterationLimit 10

Tested and working with ARTIO JoomSEF:

RewriteCond %{HTTP_URL}             (/|\.htm|\.php|\.html|/[^.]*)$   
RewriteCond %{REQUEST_FILENAME}     !-f
RewriteCond %{REQUEST_FILENAME}     !-d
RewriteRule (.*)                /index.php                      [U,L]RewriteCond %{HTTP_URL}             (/|\.htm|\.php|\.html|/[^.]*)$   
RewriteCond %{REQUEST_FILENAME}     !-f
RewriteCond %{REQUEST_FILENAME}     !-d
RewriteRule (.*)                /index.php                      [U,L]
MaxMatchCount 10

Tested and working with default Joomla SEO:

RewriteRule ^/$                      /index.php
RewriteRule ^/content/([^/]+)/([^/]+)/([^/]+)/([^/]+)/([^/]+)/ /index.php?option=com_content&task=$1&id=$2&Itemid=$3&limit=$4&limitstart=$5
RewriteRule ^/content/([^/]+)/([^/]+)/([^/]+)/ /index.php?option=com_content&task=$1&id=$2&Itemid=$3
RewriteRule ^/component/option,([^/]+)/([^/]+),([^/]+)/([^/]+),([^/]+)/([^/]+),([^/]+) /index.php?option=$1&$2=$3&$4=$5&$6=$7
RewriteRule ^/component/option,([^/]+)/([^/]+),([^/]+)/ /index.php?option=$1&$2=$3

Tested and working with sh404SEF:

RewriteLogLevel 4 #Make it 0 in to turn debugging off
RewriteLog c:\IIRfLogfile.log #Write the absolute path of your file here 
 
MaxMatchCount 10
 
# don't rewrite any request that goes to administrator
RewriteRule ^/administrator   -   [L]
 
RewriteCond %{HTTP_URL} (/|\.htm|\.php|\.html|!administrator|/[^.]*)$  
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) /index.php [U,L]

Other Third party SEO should work once to follow there rewrite conditions/rules. I run IonicIsapiRewriter-1.2.12b the betas are rock solid and I use it on my production servers with no issues. Please follow vendors installation instructions to get the ISAPI filter working on your IIS server.
