How to unset eCart Variables
I hate to have to ask this again, but the answer in the old forum could not be found.
Upon return from PayPal, I want to clear the eCart so that the user can't hit the back key, change the order and submit it again.
Eric had a nice "how to clean it up" post in the old forum, but I can't find it.
I do not want to have a wholesale session destruction, because that would entail logging the client back in.
What functions should I call to empty the cart?
