Add a Request Header to a REST Request

See more REST Examples

Demonstrates Rest.AddHeader, which adds an HTTP request header field. The 1st argument is the field name and the 2nd is the value. Adding a header whose name already exists replaces the previous value.

Background. Request headers configured with AddHeader are applied to subsequent requests sent through the object, such as Accept, Content-Type, or custom application headers.
