nice! probably no one except me will upvote this b/c its PHP which is so uncool. But I think this is a really thin, nice lib, though I would say you're gonna have problems with your REQUEST_URI if you're depending on PATH_INFO (check out the getRequestUri in Symfony2 httpfoundation for good fallbacks). I know its supposed to be micro, but you might want to consider extending the request class for other basic stuff people would like to use like HEAD / PUT / DELETE, good job though :)
