I have a site that authenticates users through NT security. Upon hitting the site users are prompted for their userID and password. I store this is a session variable for tracking where the users go and to prevent them from accessing other pages directly.<BR><BR>Here is my question. I have set the session timeout at 20 minutes. If the session expires the user is redirected to the main page regardless of where they are on the site. However the user session variable is also destroyed. How do I force IE to prompt for their id and password again when they are redirected to the main page? Or is this possible?<BR><BR>Thanks,<BR>Jeff
