-   An origin server &MAY; generate a <x:ref>Vary</x:ref> header field
-   (<xref target="header.vary"/>) in a response if it wishes to indicate what
-   fields of request information were used in its selection algorithm. This
-   informs recipients that sending more information might be useful in future
-   requests. It also warns caches not to reuse that response, until
-   reconfirmed by the origin server, for a request that contains different
-   information in those fields.
+   A <x:ref>Vary</x:ref> header field (<xref target="header.vary"/>) is
+   often sent in a response subject to proactive negotiation to indicate what
+   parts of the request information were used in the selection algorithm.
