CacheFilter: Flexible HTTP Caching in Envoy
summary
Envoy gains a pluggable HTTP cache filter that parses Cache-Control, Vary and basic ETag/Last-Modified validation, delegates storage to an HTTP cache plugin interface (C++), and performs asynchronous lookup and fire‑and‑forget inserts. The shipped demo simple_http_cache example is an in-memory hash map with no eviction or sharding and is not production ready. Missing pieces include advanced validation paths, per-route config, purge/invalidation semantics, stats, and ready-made plugins for Redis or Memcached.
