clear cart after checkout
On the checkout cart page to proceed to process payment, while it takes me to authorize.net to finalize transaction, is there any way to clear cart? or how have others similar handle this? While I see there's a checkout_failure.php and a checkout_success.php page, I'm not sure if either indeed get used here. I tried contacting authorize.net but they didn't seem to have an answer except to read their AIM documentation.
