function esi_fast_404 in ESI: Edge Side Includes 7.3

Generate a fast 404 (consisting of a single HTML comment). Full delivery is not desired, because it would typically result in embedding a complete, themed Drupal 404 page *within* another page.

function esi_fast_404() {
  drupal_add_http_header('Status', '404 Not Found');
  drupal_add_http_header('X-ESI', 'Component not recognised');
  watchdog('page not found', check_plain($_GET['q']), NULL, WATCHDOG_WARNING);

  // Unlike drupal_fast_404(), the HTML furniture (html tag, head tag, etc) are
  // not delivered
  echo "<!-- esi_fast_404 -->\n";

  // Unlike normal page-views, invoking hook_exit() is unneccessary overhead.
  // This use of exit matches the behaviour of drupal_fast_404().
  exit;
