Brien,
Thank you! That fixed the problem. I was refering to the servlet using
the URL: http://127.0.0.1:8000/servlet/LoginServlet. Inside the servlet
I was doing a redirect using the following snippet of code:
String url = req.getScheme() + "://" + req.getServerName() + ":" +
req.getServerPort() + "/"+ page;
...
res.sendRedirect(url);
...
getServerName() resolves my localhost to the fully qualified hostname
(including the domain name). Since they were two different URLs, each
were getting their own sessions.
It would be handy if there was some kind of FAQ that had answers to such
questions. I am seriously considering taking up Craig's suggestion for
the automated FAQ.
Thanks again for your help,
Anirban
