Clarifying, you *can* get the above to work as it should?

Session data in PHP is not passed as part of the HTTP request.  By
default sessions are stored in whatever container your session handler
provides (like a database, for example).  The default session handler
stores the session as a flat file in /tmp, unless you're smart/paranoid
and have changed the value for session.save_path.  What *is* passed is
the session id, via either GET, POST or cookies.

To see if the sessid is geting passed through your redirect, try:
echo session_id();
Make sure it's the same on the page before the redirect and on the page
after.

Also, the php function phpinfo() can be useful for debugging.

Did I understand your problem correctly?  If not, please clarify.
