Read the REST Response Header and Status Code

Demonstrates Rest.ReadResponseHeader, which reads the HTTP response status line and header fields after a staged send. The returned integer is the HTTP status code, or -1 if no response was received.

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.
