This header is set by our standard boilerplate VCL, generated when services do not upload any custom VCL.  It is unused and considered deprecated.

Our current [recommended boilerplate VCL](https://www.fastly.com/documentation/guides/vcl/using) for services that define their own custom VCL no longer includes this header logic.

It is a _request_ header, but set on the _response phase_, and therefore is rarely visible outside of Fastly, but may be included in a backend request if a service performs a `restart` in `vcl_deliver` or `vcl_error`, and then makes another fetch to a backend.
