I use at the first page a session variable to set a flag. After a few pages, or if somebody wait too long, the pages have another flag. I noticed that there are often more than one session file exist. How can I avoid that? How can I make sure that for one user is only one session file? bye Ronald -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
