Cache Rules Everything
summary
Only two headers actually solve HTTP caching: cache-control and ETag; remove clutter like Pragma, Expires and Last-Modified. Use directives you can reason about: example short reuses use max-age=3600, protect sensitive responses with no-store, force revalidation with no-cache, give CDNs longer life with s-maxage, tolerate stale content with stale-while-revalidate=600, and treat fingerprinted assets as immutable ≈68 years so they never need revalidation.
