next-request's preloaded stash. That is, you can load up your flash with
whatever you need, and then do a full $c->res->redirect() somewhere -- which
fires off a browser redirect and a new request -- and your then-stash will
have all the goodies you plopped in there.
And, being the stash, it's all wiped out when the request is done. So a
follow-up request (or redirect) would either have an empty stash, or it'd
require the second request-handling routines to stuff things into flash
(again).
So it's not that "flash" is permanent, it's not. It's just a pre-load for
the next-request's short-lived stash.

Why doesn't flash work across these multiple requests? I thought that was
the whole idea of flash vs. stash.

What we do is stuff the intended destination into the session and then
pull it from there:
sub login : Chained('/') PathPart('login') Args(0) {
my ( $self, $c ) = @_;
my $form = Spill::Form::Login->new( action => $c->uri_for('/login')
);
$c->stash(
template => 'login.tt2',
form => $form,
);
if ( $c->action ne 'login' ) {
# Stuff destination into session for later redirect if user
authenticates
* $c->session->{redirect} = $c->req->uri->as_string;*
}
...then, later, after authenticating...
my $go = *delete( $c->session->{redirect} )* ||
$c->req->headers->referer;
$go = '/' if $go =~ /\blog(in|out)\b/;
$c->res->redirect( $go );
$c->detach;

If a user submits a certain form without being logged in, I flash the
current URL, save the params in the session, and redirect them to the login.
In my Login controller, I look for $c->flash->{redirect_url} and redirect
them back to that URL.
The problem is that that flash entry is gone after the user submits the
login form. I logged out the redirect URL at the beginning of my login
routine and it comes through the first time, but even if I don't access it
via the log statement, that redirect_url key is not there in the flash when
the user submits the login form with their credentials.
I've tried resetting $c->flash->{redirect_url} in the login routine and
also tried $c->keep_flash( qw( redirect_url )) in the login routine, but no
go.
Any thoughts on what I might be doing wrong?
