The SendReceive() function sends an HTTP request to this REST service, and returns a
response when the data is retrieved from the service. RequestMessage contains the HTTP
request to the REST resource identified by RequestMessage.Request.Url. The
ResponseMessage is the returned HTTP response for that request, including any HTTP
status.
