There is nothing in the response which prevents it from being cached,
but nothing which makes it cached either. Typical "dynamic response with
no regard to caching". You can add expiry information to this response
with the min parameter in refresh_pattern if needed.

However, the request explicitly says the response must be fresh (or at
least verified fresh). You can override this with ignore-reload.
