I want to be able to track visitors without the use of cookies.
I don't want to rely on IP address, because people behind proxies and
firewalls seem to have the same IP address.
I don't want to rely on a session ID variable being always present in the
URL, in case the window gets closed or changed.
Now, two questions:
1) Will Apache::Session provide an environment variable like HTTP_USER_AGENT
that will contain an identifier that will always be consistent for that
specific user, despite proxies and firewalls, and despite the
changing/closing of windows?
2) If not, does anyone know of a good way to do this?
