          Web-proxies like nginx are "buffered", so they wait til the whole request (and its body)
          has been read, and then it sends it to the backends.
  
          :param int size: The size (in bytes) of the request body after which the body will
              be stored to disk (as a temporary file) instead of memory.
  
          :param str|unicode store_dir: Put buffered files to the specified directory. Default: TMPDIR, /tmp/
