    client.Headers.Add(HttpRequestHeader.Authorization, "Basic " + auth);

    try {
      client.UploadData(url, File.ReadAllBytes(input));
      /* Compression was successful, retrieve output from Location header. */
      client.DownloadFile(client.ResponseHeaders["Location"], output);
    } catch (WebException) {
