I recommend *NOT* to use session_register/unregister/is_registered().
If you really have to use session_register and others, *NEVER* use
$HTTP_SESSION_VARS/$_SESSION in your script.
BTW, you don't have to keep track session id.

If you use "trans-sid", you don't need to add session ID to your
php script (HTML part I mean)
It also handles automatic fallback from cookie session to URI session.
(Although, it sometimes fails to detect cookie for some browser. You
need additional effort to make sure use cookie when cookie is available.)

Any one can change session ID. It just only easier when session ID is in
URI :) We have to live with that.
