I am writing a server application that only allows one user to be logged in at a time. Currently I am able to block other computers by checking the IP address and looking for a match. If there is no match with the user that is logged on, then access is not given.
My problem deals with multiple instances of the IE browser on the same machine (and therefore same IP address). Is there any sort of flag that IE sends TCP/IP or otherwise that I would be able to use to determine if another instance of IE has opened? I need to be able to tell the difference bewteen one instance of the browser and another.
