Quick Reference

Use Cache-Control headers: immutable for hashed assets, max-age + stale-while-revalidate for dynamic. CDN: cache static assets at edge. Browser: leverage ETags and Last-Modified. API: use Redis/memory cache with TTL. Service workers for offline-first. Invalidate on deploy with cache busting.

Use When

  • Configuring HTTP caching
  • Setting up CDN
  • Optimizing API response times
  • Implementing offline support

Skip When

  • Real-time data requirements
  • User-specific content without cache keys
