  put_object_callback_data data;

  /*char *param = 0;

  cacheControl = "Cache-Control";*/

  //contentDispositionFilename =  filename;

  //md5 =  "base64-encoded";

  //metaProperties[S3_MAX_METADATA_COUNT].name = "x-amz-meta-foo";*/

  data.infile = 0;
  data.gb = 0;
  data.noStatus = 0;//noStatus;

  if (filename)
  {
   if (!contentLength) 
   {
    struct stat statbuf;
    // Stat the file to get its length
    if (stat(filename, &statbuf) == -1)
