Add a Query Parameter from a StringBuilder

See more REST Examples

Demonstrates Rest.AddQueryParamSb, which adds or replaces a query parameter whose value is read from a StringBuilder. The 1st argument is the name and the 2nd is the StringBuilder.

Background. This variant is convenient when the parameter value has already been assembled in a StringBuilder, avoiding an extra conversion to a plain string.
