Send a REST Request using StringBuilder Bodies

See more REST Examples

Demonstrates Rest.FullRequestSb, which sends a complete request whose text body is read from a StringBuilder and stores the text response body in a second StringBuilder.

Background. Using StringBuilder objects for the request and response bodies avoids extra string conversions, which is helpful when working with large payloads.
