I dont have any session variables. The whole purpose for me asking this question is since the web page uses windows authentication, when a internal user goes to that page, he gets the login prompt and once he logs in, the page will never prompt for login again unless he close the window.

But we need to provide a way to bring up the login prompt when the user clicks the logoff button or something so that another person can login into the page with his own credentials rather then using one credential for all the users.

I know we can close the window to get the login prompt, but thats not what i wanted.

Will be glad if anyone can shed some light on this.
Thanks again.
