Below is a piece of text I created for the Catalyst documentation a long 
time ago (perldoc Catalyst).
It tries to makes the things a little bit clearer for using uri_for_action() 
method, but it is the same in any case an action path is used.
The idea is that even though the action path looks like a URL, it is not an 
URL. It is not the URL that calls that action.

""
        Note that although the path looks like a URI that dispatches to the
        wanted action, it is not a URI, but an internal path to that action.

        For example, if the action looks like:

         package MyApp::Controller::Users;

         sub lst : Path('the-list') {}

        You can use:

         $c->uri_for_action('/users/lst')

        and it will create the URI /users/the-list.
