If I'm getting the question right, you have a cgi application on say http://www.mydomain.com/mycgi.cgi. Instead of passing parameters the usual way (ie http://blabla/mycgi.cgi?param1=value1&param2=value2), you want to pass them by using http://blabla/mycgi/value1/value2.

If this is what you need, then this is really an Apache question and what you need to use is mod_rewrite. The docs are at URL Rewriting Guide. Here is a glimpse of what you need to add to httpd.conf or .htaccess:

RewriteEngine on
RewriteRule    ^/mycgi/([^/]+)/([^/]+)\.htm$    /mycgi.cgi?param1=$1&p
+aram2=$2 [R]
[download]

I have not tested this, but it should not be far. And I don't know about IIS.

Hope this helps
