I use PHP. I want to setup a micro site as a prototype, where I can work with the frontend only, separated from any CMS.

URL Rewrite

I also want the URL rewrite to be correct, like http://www.test.com/products/tables/green/little-wood123/

Question(s)

1. Is there any free class for URL rewriting? I searched but found none.
2. If that is not the way to go, what framework is nice for this? It should be tiny, easy to use and support URL rewrite.
