Get a REST Response Header Value by Index

Demonstrates Rest.ResponseHdrValue, which returns the value of the response header at a zero-based index. The same index used with ResponseHdrName gives the corresponding field name.

Background. Response headers can be enumerated by index from 0 through NumResponseHeaders minus one, after ReadResponseHeader has been called.
