unset session when ?
I have successfully included code to unset all sessions on checkout_success and checkout_failure.
in testing, i have found that if i don't visit these pages after paypal, and just go back to my site, whilst keeping the browser open, my sessions are still active.
Were I to unset the session on the checkout confirm page, would this cause any issues with my IPN validation.
If not, at what point should I unset the session, presumably only when the confirm button is clicked ?
