I just pop up the login form on the requested page - i.e. $c->detach('/login')
or so.

Then I handle the login in the same place (Root::auto or an early Chained part
depending on the app) as I'd normally check permissions, so if the login
succeeds the basic Catalyst dispatch already done executes the right code
automatically.

The only trick to this is calling the login form fields __login__username or
similar so that they're guaranteed not to clash with anything else.
