Enumerate REST Response Header Names
See more REST Examples
Demonstrates Rest.ResponseHdrName, which returns the field name of the response header at a zero-based index. The example enumerates all headers, pairing each name with its value.
Background. Response headers can be enumerated by index from 0 through NumResponseHeaders minus one. ResponseHdrName and ResponseHdrValue use the same index for a given header.
