    setRequestHeaderValues();
    final int code=httpClient.executeMethod(getMethod);
    if (code == HttpURLConnection.HTTP_PARTIAL || code == HttpURLConnection.HTTP_OK) {
      getResponseHeaderValues();
      setInputStream(((GzipGetMethod)getMethod).getResponseBodyAsUnzippedStream());
      fireReceiveStartEvent();
    }
 else     if (code == HttpURLConnection.HTTP_NOT_FOUND) {
      getMethod.releaseConnection();
      throw new FileNotFoundException(urlString);
