But they're using the same URL both times.  It's not a redirect, or
changing the root path, but different content.  You can do pretty much
anything you want based on whether the user is logged in.  It seems
rather hackish, but you could have your controller send an entirely
different set of vars and have the view use an entirely different
section.  You could at least keep it somewhat clean by separating the
two views into partials or some such....
