I was trying to write a module where the user asks for a particular URI but 
for certain reasons ( say session expired or not yet logged etc. ) has to be 
authenticated again and then user will be automatically redirected to the 
requested page,in a way furnishing something before actual request is 
processed. 
For this I saved the URI requested ( say as $path ) as a session variable, 
redirected to the authentication page ( say to the standard login page ). But 
the issue was to redirect to the page requested by the user for which I got 
back the URI path from the session variable, till here all fine. But without 
knowing the action for that URI name I cant forward to it. That is where I 
needed something like 		$c->forward(controller_path(uri));

Or is there another approach to this problem.

The dispatcher does produce the list of all the actions, but the process is 
complicated, if there is a way access the list of all actions that it 
produces then may be have to parse through the list to identify the right 
action.
