…esponse caching Assigning heuristic freshness to a response with a query component is no longer prohibited by the HTTP caching specification, so the CacheConfig options that suppress caching of such responses no longer serve a purpose. isNeverCacheHTTP10ResponsesWithQuery, isNeverCacheHTTP11ResponsesWithQuery and their builder setters are deprecated, as is HTTP/1.0 response caching itself. The options are still honoured for now; an origin that does not want a response cached should send an explicit directive such as Cache-Control: no-cache.

RFC 9111 section 4.2.2 no longer prohibits assigning heuristic freshness to a response with a query component; the earlier RFC 2616 section 13.9 prohibition was obsolete and not widely implemented. The CacheConfig options that suppress caching of such responses therefore no longer serve a purpose, so isNeverCacheHTTP10ResponsesWithQuery, isNeverCacheHTTP11ResponsesWithQuery and their builder setters are deprecated, as is HTTP/1.0 response caching itself. The options are still honoured for now; an origin that does not want a response cached should send an explicit directive such as Cache-Control: no-cache.
