There was a problem hiding this comment.
@arturobernalg Why? Why not making it a proper context attribute like CacheResponseStatus, RequestCacheControl, ResponseCacheControl, etc?

Adds optional support for the RFC 9211 Cache-Status response header to the caching executors.
When enabled, the cache records how each response was produced — a cache hit,cor a forward to the origin with the reason (bypass, method, uri-miss, vary-miss, request, stale) and the upstream status code where relevant — and emits a
Cache-Status header identified as Apache-HttpClient.
Disabled by default; enabled with
CacheConfig.setCacheStatusEnabled(true).Applies to both the classic and async cache execution paths.
