Get a REST Response Header by Name

Demonstrates Rest.ResponseHdrByName, which returns the value of a response header field by name. Header field names are case-insensitive.

Background. Response headers are available after ReadResponseHeader has read the status line and headers. Lookup by name is convenient when a specific header, such as Content-Type, is needed.
