Note Submitter: trisweb@hotmail.com ---- Just a note about some of the variables mentioned in the notes on this page -- most of them are $_SERVER[] vars, so you may have pull them from the $_SERVER array. Many of the examples assume register_globals is on, which it isn't by default in recent versions. So, $HTTP_HOST and $REQUEST_URI are actually $_SERVER['HTTP_HOST'] and $_SERVER['REQUEST_URI']. Gotta watch out for all the register_globals stuff... and don't just turn it on to make things easier for you. ;-)
