They capture groups and can access them later yes. who care ? A lot of urls rewriters are not using regexp because it adds an extra layer of complexity: webmachine in erlang, werzeug in python, ... > 3. Everybody knows them that's not true. http://xkcd.com/208/ To answer to this "reinventing" . We had long discussions on how to manage rewriting in couchapps. Some included "regexp", we fall in the current system. Ie pattern matching because it was a lot easier to understand and *simple*. SInce the system is already in place, I wanted to reuse it too, there is no need to have 2 dofferent ways to handle rewriting. I would like to keep it *simple*, that's the key. Anyway, can we go back to the topic ? I still don't understand how vhosts in 1.0.1 or in trunk are a problem ? About that I'm thinking we could propse a request_handler that isn't relying to vhost at all and make them an option, would it be ok ?
