Subject RE: JDBCRealm - Session not timing out
Date Thu, 10 Jul 2003 18:07:53 GMT
Adding objects:

HttpSession session  = request.getSession();
session.setAttribute("foo", "Foo");

If at some point in your code, you want to "log out" a user,
Then when they request a protected resouce , the container "ought" to
re-authenticate them through FORM auth, because the session is where the
container "ought" to store this info.  But Again, I don't *know* this
for certain.

There are plenty of other methods of interest on session.  You might
also read the javadocs for request.getSession() and the differences when
you supply a boolean parameter in that method.
The jsession_id in your addressbar means only that the server cannot
determine (yet) if cookies are enabled on your client, and has
re-written the URL to contain the (in your case new) session id. Once
cookies are confirmed, the URL is no longer rewritten, unless you
container supports a configuration where URL rewriting is *always* done
(like iPlanet).

Which seems to indicate that a session has been created.

Now, if it has been created, how can I use it?  I would like to add my
to the session object.
