  15  * This script processes "Instant Payment Notifications" (IPNs).  Modern
  16  * Payment Processors use the /civicrm/payment/ipn/123 endpoint instead (where
  17  * 123 is the payment processor ID), however a quirk in the way PayPal works
  18  * means that we need to maintain this script.
  19  *
  20  * Note on PayPal.
  21  *
  22  * Using PayPal Website Standard (which uses the old PayPal button API) the IPN
  23  * endpoint is passed to PayPal with every transaction, and it is then stored
  24  * by PayPal who unhelpfully do not give you any way to retrieve or change
  25  * this.
  26  *
  27  * This means that if you provide URL1 when setting up a recurring
  28  * contribution, then you will always need to maintain URL1 because all
  29  * recurring payments against that will be sent to URL1.
  30  *
  31  * Note that this also affects you if you were to move your CiviCRM instance to
  32  * another domain (if you do, get the webserver at the original domain to emit
  33  * a 307 redirect to the new one, PayPal will re-send).
  34  *
  35  * Therefore, for the sake of these old recurring contributions, CiviCRM should
  36  * maintain this script as part of core.
