I have seen similar behavior with Netscape browser. It was caused
by port number included in URL. Following URLs:
http://mymachine/servlet/MyServlet
http://mymachine:80/servlet/MyServlet
http://mymachine.mydomain.com/servlet/MyServlet
http://mymachine.mydomain.com:80/servlet/MyServlet
are treated as different servers so you cannot share sessions
among them. Check if this is your case.
