Abstract:
   The 'Key' header field for HTTP responses allows an origin server to
   describe the secondary cache key ([RFC7234], section 4.1) for a
   resource, by conveying what is effectively a short algorithm that can
   be used upon later requests to determine if a stored response is
   reusable for a given request.

   Key has the advantage of avoiding an additional round trip for
   validation whenever a new request differs slightly, but not
   significantly, from prior requests.

   Key also informs user agents of the request characteristics that
   might result in different content, which can be useful if the user
   agent is not sending request header fields in order to reduce the
   risk of fingerprinting.
