On his PHP Genious blog Timir Shah has written up a new post looking at how you can configure URL rewriting (much like mod_rewrite) in an IIS7 web server running PHP applications.

Few days ago, I faced a URL rewriting problem on windows server. After checking the server configuration, I found that there is an II7 installed. After long research about this, I found that II7 is not support .HTACCESS. If youwant to male your site SEO URL friendly, then you have to use web.config file for URL rewriting instead of .HTACCESS. Now the question is how to make web.config file from .HTACCESS?

He compares the two formats, showing how different directives from the .htaccess file can be translated over. He starts with an example of default documents on either side - the .htaccess defining several "php_value" settings and the web.config setting some default routing and rewrite rules. He shows how to set up a few things on each side - error page redirects and setting up some custom URL rewrite rules for both sides (with examples).
