>I have a questions regarding the the MapHttpRoute method (above). I read in a book that "the MapHttproute method simply adds a new entry in a dictionary that stores all the routes." Where is this 'dictionary'? In which format is it?

It's created by the system. I *think* you can inspect the entries via GlobalConfiguration.Configuration.Routes (it's a collection of HttpRoutes).
