Abstract
To aid debugging, HTTP caches often append header fields to a response, explaining how they handled the request in an ad hoc manner. This specification defines a standard mechanism to do so that is aligned with HTTP's caching model.
For the definition of Status, see RFC 2026.
For the definition of Stream, see RFC 8729.
