+Tutorial - The default method
+
+Request handler objects can implement a method called "default" that
+is called when no other suitable method/object could be found.
+Essentially, if CherryPy2 can't find a matching request handler object
+for the given request URI, it will use the default method of the object
+located deepest on the URI path.
+
+Using this mechanism you can easily simulate virtual URI structures
+by parsing the extra URI string, which you can access through
+cherrypy.request.virtualPath.
+
+The application in this tutorial simulates an URI structure looking
+like /users/<username>. Since the <username> bit will not be found (as
+there are no matching methods), it is handled by the default method.
