Causes the object publishing machinery to continue on with specified resource and segments, calling the appropriate method on the specified resource. If you return (self, L{server.StopTraversal}), this instructs web2 to immediately stop the lookup stage, and switch to the rendering stage, leaving the remaining path alone for your render function to handle.
