Perform Function when...

I was also thinking that the SESSION array was included.

thats what I meant to say... but my fingers typed SERVER instead... haha I didnt even catch that until you posted.

Ha. Ok. But SERVER makes some sense too. the IP, REQUEST_URI, HTTP_REFERER, brower info, etc., are input in some sense.

I like to stay away from $_REQUEST, anyway. Too much guesswork involved. If I do need to use both post and get (and/or cookie), then I just write that directly, explicitly, so it's easy to keep track of.
