Always use strict. Always use strict! With -w you get a warning only.

You are using two variables $cookie, one here 

if ( !$sid or $sid ne $session->id ) {
    my $cookie = $query->cookie(
        -name  => 'test',
        -value => $session->id,
        #-expires => ''  makes it so on close session expires.
    );
}

and the other here: 

print $query->header( -cookie => $cookie ), $template->output;

At the first place, the my variable $cookie is confined to the if () { ... } block, so you are not re-using that at the second place, where $cookie is a package global. See Lexical scoping like a fox.
