Edge Caching Trends and Misuses 2026

Edge caching is more powerful than it gets credit for. The patterns that work and the mistakes that kill cache hit rate.

Wins

Static content: trivial, well-supported.

Personalised content: cache by user-segment, not per-user. 80% hit rate is achievable.

Cache by user ID: each user gets their own slot; effective cache is zero.

Cache forever: stale content shows up; regenerate is forced more rigorously than expected.

Hit rate per route. Below 70% is suspect for cacheable content.

Origin egress: should drop as edge hit rate climbs.
