blackbull.middleware.cache

Response caching middleware (RFC 9111 — HTTP Caching).

Caches successful GET/HEAD responses in a per-worker, in-memory LRU and replays them without running the handler. It reads Cache-Control in both directions, generates a weak ETag when the handler supplies none, answers If-None-Match with a 304, and keys variants by Vary. There is no invalidation API and nothing is shared between workers: restart the worker, or wait out the lifetime. docs/guide/middleware.md tabulates the constructor.
