Send a Staged Multipart REST Request
See more REST Examples
Demonstrates Rest.SendReqMultipart, which sends a multipart request using the parts configured on the object, then reads the response in separate steps.
Background. The staged request model separates sending from reading: a
SendReq method transmits the request, ReadResponseHeader reads the status line and headers, and a ReadResp method reads the body. This gives fine control over large or streamed messages compared with the single-call full-request methods.Chilkat Android™ Downloads
