Yes there is a neat trick. What u do is create an Applet in your web page. &
when the user closes his Browser window. Its destroy() method is called. So
in this method just call a Servlet say LogoffServlet which invalidates this
users session from the Context or whatever your logics is. Now the User is
Free!!. So he can rightfully login from another Place.
Bye
