Is it possible to write a route that would be executed even on partial uri.
Suppose I have uri like :/module/controller/action/param1/val1.... Then next route works fine
<?php
$router -> add ('/:module/:controller/:action/:params', array(
    'module' => 1,
    'controller' => 2,
    'action' => 3,
    'params' => 4
));But when only part of the uri supplied, like /module/controller/ this route doesn't work.
Is it possible to make a route that would use defaults when only part of uri matched. Like when only module name is supplied, default controller would be used and so on.
