Did you talk about the same physical user? if yes you should verify that a specific variable/object in the user scope has not a specific value/state.
if you talk about protecting a session to be opened twice or more from many differents users, you should need some checking on the domain scope by storing each new active session. If you detail a bit more perhaps someone could add some propositions hope this helps Gauthier ----- Original Message ----- From: "Marc Leblanc" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, January 28, 2003 9:04 PM Subject: Witango-Talk: Blocking users from entering twice > > Hi, > > What would be the best solution to block a user from entering a site twice. > Or, in other words prevent other users to use a same login.
