We are adding a layer of security to our Intranet, and what I am trying to do is allow a person to click a button and login as a different user. We are using LOGON_USER to determine who the user is. Is there any way to clear the LOGON_USER variable, or even a way to overwrite the existing information? <BR><BR>I&#039m trying to avoid having the user close the browser in order to log in as someone else.<BR><BR>Any help would be greatly appreciated.<BR><BR>Joe
