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.

-- Important: See this note about string length limitations for strings returned by sp_OAMethod calls.
