Joe, Presently MultipartFormEntity cannot be repeated if length of any of its parts is unknown, which is the case with body parts backed by a InputStream or a URL. In your particular case, however, given that URLs represent local resources you should be able to convert them to File instances and thus make their length known in advance.
