------------------------------------------------------------------------
RFC 9111, section 4.1
* When a cache receives a request that can be satisfied by a stored response
and that stored response contains a
[Vary|https://httpwg.org/specs/rfc9110.html#field.vary] header field ([Section
12.5.5|https://httpwg.org/specs/rfc9110.html#field.vary] of
[??[HTTP]??|https://httpwg.org/specs/rfc9111.html#HTTP]), the cache _MUST NOT_
use that stored response without revalidation unless all the presented request
header fields nominated by that Vary field value match those fields in the
original request (i.e., the request that caused the cached response to be
stored).
-Under our existing system architecture, we have yet to implement the Vary
header validation as specified in these requirements-
Edit: [~arturobernalg] We are actually fine. The variant key is composed of all
request field values designated by the Very header. The cache lookup for a
variant entry will produce no hit unless all Vary field values fully match.
