Caching Strategies for Web Performance 🚀

1. Browser Caching 🌐

  • Enable Cache-Control headers: Set max-age for static resources like CSS, JS, and images.
  • Use ETags and Last-Modified: Help browsers validate cached content efficiently.
  • Leverage Service Workers: Implement custom caching logic for dynamic assets.

2. CDN Caching ⚡

  • Distribute static assets globally: Reduce latency with edge servers.
  • Set TTL (Time to Live): Define how long content is cached at CDN nodes.
  • Optimize for regional users: Route requests to the nearest server for faster delivery.

3. Server-Side Caching 📦

  • Cache database queries: Store frequent results in memory (e.g., Redis).
  • Use reverse proxies: Tools like Varnish cache HTTP responses.
  • Implement caching layers: Combine CDN, browser, and server caching for optimal performance.

4. Cache Invalidation 🧹

  • Automate invalidation: Use Cache-Control: no-cache for dynamic pages.
  • Monitor cache hit rates: Adjust strategies based on traffic patterns.
  • Combine with CDN purges: Ensure stale content is removed promptly.
