When not explicitly set, a cookie works only for the domain where it was originally set. That means that if the user visits your website using the server IP address, he will receive a cookie that will not work when he uses the domain name instead of the IP address. Therefore, I recomend you set the domain property of the cookie to the name of your domain (not the IP or "localhost"). This way, you will make explicit in which enviroment the cookie works. I am not familiarized with the sintax you are using, I usually use setcookie and session_register for a similar purpouse. Hope I'd been of any help. Cheers. PD. Why don't you publish your problem to the whole php list? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Thursday, 18 January, 2001 9:59 AM To: [EMAIL PROTECTED] Subject: [PHP] help me!!
