[Devel] Re: Methods filtering

[Bogdan-Andrei Iancu]

in openser, module functions may return more than true or false - there 
is the return code variable "$?" or "$retcode" which may be tested. 
usrloc may return -1 for not found at all and -2 for found but not 
matching method:
    ....
    lookup(location);
    switch($?) {
       case -1:
          sl_send_reply(404);
          break;
       case -2:
          sl_send_reply(405);
          break;
    }
    t_relay();
    .....

regards,
bogdan
