Re: [mp2] reliable methods to prevent handlers from repeating

[Dorian Taylor]

here's my solution to handler loop prevention when the initial
request to a handler isn't necessarily the main request:

sub handler {
    my $r  = shift;
    my $mr = $r->main || $r;
    if ($mr->notes->get(__PACKAGE__ . '::SEEN')) {
        $r->log->debug("We are looping.");
        return Apache::DECLINED;
    }
    $mr->notes->set(__PACKAGE__ . '::SEEN', 1);

    # ... do stuff, including other lookup_uri/lookup_file requests.

    $mr->notes->unset(__PACKAGE__ . '::SEEN');
    return Apache::OK; # or whatever other status
}

comments?
