Stefan
I do have the session_start() in my script, the code I included in my
original script was just and extract from that script.
But my problem is not that I can't perpetuate the session id after coming
back from the credit card company. My problem is that I want to delete the
cookie from the users' browser, and at present I am trying to do this from
within the script that is called from the credit card gateway's
confirmation.
