Code

function fb_app_event_cb($event_type) {

  // Events are passed 'fb_sig' params, so globals should be set.

  if (!$_fb_app) {
    drupal_not_found();

    'event_type' => $event_type,

    'fb' => $_fb,
  ), NULL);

  // This page is called by facebook, not a user's browser.  User's should never see this.
  print 'Thanks Facebook, for your fancy API!';

  // It's facebook calling us, not the user.  And fb_sig params make it look
  // like a canvas page, but it could be connect.  So bad idea to save session.
