Send a Staged REST Request with No Body

See more REST Examples

Demonstrates Rest.SendReqNoBody, which sends a request without a body as the first step of the staged request model. After it succeeds, the response header and body are read separately.

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.
