I have a web application (JSP, Servlets) running on Tomcat 4.2, Linux 9, jdk 1.4. When I browse the application using IE 5.5/6.0 the session is properly carried throughout the application but when I browse using Netscape 4.7 the session variables are not carried. Any suggestion / comments to solve the problem ?
Is your Notscape configured to reject cookies maybe? If so the session information (which is carried in a cookie) is lost between requests.
A question: is there a hard requirement to support Notscape? If not, drop it. From some research I did last year when working for an e-commerce site we discovered that the percentage of Notscape 4 users was well under 1% and dropping. That includes ALL minor versions, which are not even compatible with each other so you need to write code for all of them.
Are you maybe trying to access the same session through different windows generated with the New Window menuoption (Ctrl-N)? This works as expected in IE where all windows in the same process share a session, in Notscape it doesn't work and all windows will get different sessions (this is a known problem with Notscape).
