On the SaniSoft blog, Tarique Sani talks briefly about some of the prefix "automagic" that's already built in to the CakePHP framework's routing.

There are times when you need more than just admin routing, how about something like http://blah.com/user/profiles/edit and http://blah.com/user/profiles/changepassword ? If this could be routed to an action like user_add and user_changepassword wouldn't it be great!! (eg: think ownership ACL checks)

Good thing the CakePHP developers already planned for something like this - they included the connect() method for Router objects that maps the URL request to a method with that same prefix in the controller.
