You can check window.opener.location property. That should have a URL of the page which opened your page.

Whenever some user logs in to a system, it actually creates a new session. Just store the Session id againist IP address in the database whenever the user logs in. Now create one handler from which check every request. Use IRequiresSessionState to get the session id. If the session is found in the database for the same IP, Server.Transfer to Logout page with a particular error. This way no more than 1 login would be allowed from the same IP. Remember : You should delete the entries as soon as the user logs out. Also you need to place a trigger which would automatically delete one record when Session expires in the server for the IP, so that if one user forgets to logout, he could login again after a certain Timeout range. Cheers. :rose:

This is a different thing. I assume he meant you should not be able to do Right click -> Open in new tab on any of the link. If he does, then he should be signed out.

That cant be done. Bcos in case of Firefox Session will be the same if you open a new tab. That is why if you login on an account using firefox, it will automatically transfered(which is of course not the case with IE) Might be he can disable right click .... :laugh:
