I use IIS mod_rewrite and CNCat 2.1 from cn-software.com.
I use IIS 5.0 and PHP 5.1.2

I want to use Search Friendly Urls but everytime I do that I have to write a whole list of urls to rewrite

like this example:

RewriteRule ^/dir/diritem1/ /index.php?o=0&c=1
RewriteRule ^/dir/diritem1/ /index.php?o=1&c=1
RewriteRule ^/dir/diritem1/ /index.php?o=2&c=1

RewriteRule ^/dir/diritem2/ /index.php?o=0&c=2
RewriteRule ^/dir/diritem2/ /index.php?o=1&c=2
RewriteRule ^/dir/diritem2/ /index.php?o=2&c=2

I want to use this where all I have to do is write this once:

RewriteRule ^/dir/(.*) /sefriendly.php

What I was wondering is how can I make it to where every time I add a category in the admin area the Category works and none of this adding more to the list.

I accidently deleted this list and I don't want to rewrite the list again

How can I make this easier?

Knowing which URL rewriting component you are using would help to get you an answer

I don't know which could be writing urls. Do you have any sugestions. Could it be sefriendly.php. Does this mean I have to use apache to write urls?

To do do "SE Friendly" URIs on IIS normally requires a component to be installed on the server, ISAPI_Rewrite being the most well known.

whatever CNCat is, it probably uses the apache mod_rewrite module.
