Subject RE: Very strange session problem on localhost only (trying again)
Date Wed, 22 May 2002 15:00:28 GMT
Scott,

The session object is created by Tomcat, as a session cookie.  Maybe it's
possible that IE destroys that cookie when the popup window is closed or
something?  There is no java code executed when the popup window is opened,
then link just has some javascript like shown below...

onclick="return window.open('/html/cust_serv.html');"

This pops up a window, when I close that window, with the 'X' in the top
right of the browser, then try to click on a link in the original window (a
jsp), I find that a new sessionID has been set.

So, without executing any java code at all, the session ID is switched by
simply opening a new window.

Hi Brandon,

This is really more of a Java question; if you could post a snip of your
code relative to the problem, it would be helpful. Particularly useful would
be the code that you're using to create the HttpSession object. The only way
that I can imagine your problem could occur is if the servlet were creating
a new session for each request.
