The browser is not even required to provide a Referer header, so you 
shouldn't rely on it.

You should use a hidden item in the form to provide some known piece of 
data so you'll know where it came from.

This "form" script's action property is set to recall itself. The thing is I'm trying to check (within scriptB) to see if the current script and the previous script are the same - when I make that recursive call back. First time the form gets submitted, the 2 are different still because the referer is still known to be scriptA and not scriptB. Is there a simple way to replace scriptA with scriptB first time when the form loads?
