In OpenInteract we use the idea that a URL is nothing but a remote procedure call. For instance: /User/list/ lists all users, and /User/list/?last_name=wall finds all users whose last name has 'wall' in it. This idea isn't anything new: Jon Udell talks extensively about it in Practical Internet Groupware and other projects use it as well.

What does this mean practically? You need: (a) a map of URL name to Perl action (b) a multiplexer that catches every request, reads the map and executes the matching action. This might sound more complicated than it is -- it's basically another version of your pseudo-case statement above, but once you start separating the pieces (putting the URL -> action map in a separate place from your script), then you can really start flying. And the general pattern is simple enough to work in CGI or mod_perl.
