private Source getTransferStream(Response response) throws IOException {
  if (!HttpHeaders.hasBody(response)) {
    return newFixedLengthSource(0);
  }

  if ("chunked".equalsIgnoreCase(response.header("Transfer-Encoding"))) {
    return newChunkedSource(response.request().url());
  }

  long contentLength = HttpHeaders.contentLength(response);
  if (contentLength != -1) {
    return newFixedLengthSource(contentLength);
  }

  // Wrap the input stream from the connection (rather than just returning
  // "socketIn" directly here), so that we can control its use after the
  // reference escapes.
  return newUnknownLengthSource();
