code: public static synchronized void cancelNetworkCall(String url, String requestMethod, long endTime, String exception) {
      if (url != null) {
        String id = sanitiseURL(url);

docs: When a network request is cancelled we stop tracking it and do not send the information through.
  Future updates may include sending the cancelled request timing through with information showing it was cancelled.
