I have a working webapp based on CGI::Application which at the start of each request redirects the user to a login page if an appropriate cookie is not found.

This is achieved in cgiapp_init (simplified somewhat): 

sub cgiapp_init {
    my $self = shift;
    my $user = $self->get_user_from_cookie();

    unless ( defined $user ) {
        print $self->query->redirect('/login.pl');
        exit;
    }

    $self->{user} = $user;
    return 1;
}

I would much rather have some better way of exiting than just calling exit. It would be nice to have some form of variable/flag that could be set to stop the execution of the remaining functions but would let things like the teardown run.

How have others dealt with this?
