I was wondering if anybody could help me with session handling in a Java
Servlet. Here's the problem that I'm having:
The application that I'm working requires me to be notified when a user
either a) jumps to another webpage or b) closes the browser window. In
order to do that, I'm using the JavaScript onUnload() function. When a
user points his/her browser in another direction, the onUnload() tag causes
a new browser window to open up which is pointed to my servlet. Now, I
need access to the session that was created previous to the user jumping
off my servlet. However, when I try to call getSession(false) it is
returning null back to me. Is there any way to keep the session alive?
On a side note, is there any way in Java Servlet programming to determine
whether or not the user is still on your page? I would like to avoid using
the onUnload() JavaScript function if possible.
Please help,
Raj
