Rachel:
Just want to point out that "req.getSession(true)" will create a new session if
one doesnt already exist. If you want to make sure that a person doesnt get a
session unless they come in "through the front door" of your loginServlet, you may
want to do something like this:
session = req.getSession(false);
if (session == null) redirect to loginServlet;
else carry on.
Hope this helps.

me know if I have misunderstood your problem; shall have time to look at it later
