Response Caching

1# Response Caching — v2 (v2.6.0+)
2# Requires Redis. Entity-level and root-field caching for subgraph responses.
3# Subgraphs must return Cache-Control headers for caching to take effect.
4# See references/response-caching.md for full setup, invalidation, and observability.

15    # so the router can cache per-user.  The subgraph must also return
16    # Cache-Control: private (via @cacheControl(scope: PRIVATE) in Apollo Server,
17    # or by setting the header directly in other frameworks).
