No, there is no such thing as forwarding to a URL.

You forward to a 'private path'. This may, or may not correspond to a  
dispatchable URI.

Erm, that's forwarding to a component name and a method name, and I  
don't think ^^ will work, as it's not a component which will be  
returned by $c->component.

This is forwarding to a class name without a method name, and so the  
method name defaults to 'process'

You don't fully qualify the namespace - you just say ->forward 
('View::XXXX');

The other thing is that you've missed the most important and useful  
thing you can forward to - an action directly.

$c->forward($c->controller('Foo')->action_for('bar'), [@args]);
