[Catalyst] Usage of $c->uri_for and $c->res->redirect

[Dustin Suchter]

Let's say I want to send people back and forth between an HTTP 
connection and an HTTPS connection on a server based on some action. For 
example, clicking on a "logout" button from within my application while 
connected via HTTPS does something like:

$c->res->redirect("http://foo.com/");

The above seems like a fine solution except it totally disregards the 
beauty of uri_for, which I would love to be using for stuff like this. 
Without uri_for, problems arise when you do things like test via the 
built in Perl webserver (the one running on port 3000 by default) while 
on the same webserver as my "production" application.

So the real question is, how do I properly refer to my webserver and/or 
application root and include port or SSL flags? I guess I'm looking for 
something like $0 within uri_for.
