That's not entirely correct: PayPal's interface does permit the merchant
to specify a URL to which PayPal will transfer control once the business
at PayPal's site is concluded. If the user cancels the transaction at
PayPal, that won't happen, of course, but if he completes the
transaction, PayPal will send him back to whatever URL the merchant
supplied to PayPal as the "return address".
