Why on earth would you want to do that?  The normal demo has no session
management.  If you want to run the session demo, use
demo/session_demo.cgi.

Oh, I think I see what's happening.  You're using SessionPublisher, but
you're not using the DemoSession class in session_demo.cgi.  You'll have
much better luck if you use session_demo.cgi instead of hacking demo.cgi
to serve up the session demo.

That's because you're trying to use non-persistent sessions with a plain
CGI driver script.  As I state several times in the documentation, this
will not work.  Use session_demo.cgi.
