In the examples below, each time you view one of these pages in a browser
with *cookies disabled* you should get a different session created
(pointer/reference and session id will be different) - the server cannot
know what the session ID is.
The cross links in the pages are built using encodeURL, if you click on
these links you should see the session object then remain constant across
the two pages.
I tested this using JRUN 2.3.3 and it works as I describe.
In my case the encoded url becomes something like this:
/test/session2.jsp?jrunsessionid=944650284078244912
(JSWDK-1.0.1 will be a bit different but the principle should be the same)
Note: change the '/test/' bit to the directory where you put the files.
If these example files don't work then I think you may have a bigger
problem... :-)

The default value for the session attribute in the <%@ page %> page
directive, is 'true' so a session should always be created for you, so you
shouldn't need to use request.getSession(), as the 'session' object in JSP
should already be set/created for you.
Hope that helps,
Steve
