If a human is involved you can't really do anything about it other than slow them down. If they're doing this a lot you can implement some backend server tracking. It is really hit and miss, but you can try tracking by IP, but proxies make this fail. You can also make sure that you require sessions. That might help a bit but a user can always clear their cookies. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
