I'm trying to do another SEO system with PHP/.htaccess...

I need the following rules to apply:

  1. Must catch all URLs that do not end with an extension (www.foo.com --> catch | www.foo.com/catch-me --> catch | www.foo.com/dont-catch.me --> don't catch).
  2. Must catch all URLs that end with .php* (.php, .php4...) (thwaw are the exceptions to rule #1).
  3. All rules must only apply in some directories and not in their subdirectories (/ and /framework so far).
  4. The htaccess must send the typed URL in a GET value so I can work with it in PHP.

Any mod-rewrite wizard can help me?
