That was a really silly question.

"Does X really work" is basically saying "are the developers idiots?". If it
didn't work, we'd have a failing test case and be trying to write a patch or
it'd go into the docs.

Of course, flash by its nature isn't always safe under e.g. multiple tab
situations etc. but that's down to -what- it is, not the implementation.

Ok, so at this point you haven't changed the URL at all. Why bother changing
it?

What I usually do is $c->forward to my login action, which tests for
__login_user and __login_pass fields and if present, tries to login. If
that works, it just returns and the request goes on as normal. If not,
it sets up the login form and does $c->detach.

For bonus points you can save the POST params (if any) and the HTTP method
(if not POST) into the login form so you can provide the exact same
environment - you can't redirect to a POSt request but you -can- allow
one to continue ...
