  // Issue #1242416: Set a nocache cookie on a POST, remove it immediately after
  // (on GET) Only necessary for anon users, since we already do not cache for
  // logged in users. Also note that if we are processing a GET, it means that
  // we have already been through the htaccess rules, so the cookie has done
  // its job and can be removed.
