Send a Form-URL-Encoded REST Request

See more REST Examples

Demonstrates Rest.FullRequestFormUrlEncoded, which sends an application/x-www-form-urlencoded request. The body is built from the query parameters added to the object, and the response body is returned as text.

Background. For a form-url-encoded request the accumulated parameters become the request body rather than the URL query string. This matches the encoding used by HTML form POSTs.
