Nooku Framework

There's a new plugin in Nooku Server Alpha 4 that rewrites URIs to stylesheets, script, images and css urls. Rewrite how? To support Expire headers by making each URI unique by adding the file's modified timestamp as a query variable. That way it changes whenever the file does, and never unless it does. So it's possible to set expire headers to max.

Recommended Apache configuration for expire headers
