Caching and headers

That implies a controller "Styles" with method "css". If you are going to go the route of writing a controller/method for each mime-type you attach to a given URI, I wouldn't consider that DRY enough for my tastes. Remember, your main requesting routes will run through the controllers that send HTML. From within that HTML, you will be making calls to a CSS URI and a JS URI with "link" tags and "script" tags. That's two more controllers that you will have to write to effectively accomplish one request. It just gets worse from there if you want to create RSS feeds or apply XSLT.

Simply recognizing the suffix will give you enough flexibility to extend CI's rendering abilities while still based around a common URI.
