      Check whether the we should overwrite the content type for the outgoing request.
      Parameters:
        `msgContext` - MessageContext
      Returns:
        whether to overwrite the content type for the outgoing request

    - #### isEmptyPayloadStream

          public static boolean isEmptyPayloadStream​(InputStream inputStream)
                                              throws IOException
