  if (isset($_SESSION['cache_expiration'])) {
    $expire = REQUEST_TIME - $cache_lifetime;
    foreach ($_SESSION['cache_expiration'] as $bin => $timestamp) {
      if ($timestamp < $expire) {
        unset($_SESSION['cache_expiration'][$bin]);

    }
    if (!$_SESSION['cache_expiration']) {
      unset($_SESSION['cache_expiration']);
    }
  }
