When you start a Sessions PHP creates a Session ID. This is then used to create/Store information in a file or in a database. The configuration of this is in your php.ini file. If this file you can change where the session is saved as well as other options. A simple way to use Sessions is with cookies with the session.use_cookie = 1 in the php.ini file. However, if the client doesn't allow cookies there is a second way; session.use_trans_sid = 0 there are a few problems however, it creates a security risk. Anyway, I hope this opens a little on how sessions works. If you wish to learn more about sessions go to http://us2.php.net/session or http://w3schools.com/php/php_sessions.asp David Wonderly WebGenero
