Send a REST Request with a Streamed Body

See more REST Examples

Demonstrates Rest.FullRequestStream, which sends a complete request whose body is read from a Stream, then returns the response body as text.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background. Streaming the body is appropriate for large uploads because the data is read incrementally from the source (here a file) rather than being held entirely in memory.
