mod_cache and User - Friendly URL

["Drkwv Drkwv" <bl3.drkwv@xxxxxxxxx>]

Hi, All.
To provide User - Friendly URL on my site, I'm using a PHP script + mod_rewrite directive, that rewrites all requests to the "index.php". How I can use mod_cache module to cache requests in that case?

Problem is that mod_cache caches only first request to index.php. Probably, I can add requested URI to the GET query string using mod_rewrite, and that request will be cached according to RFC 2616/13.9, but I think, this is not a best way to cache server content. Is there another way to do that?
