Caching

Caching Strategies to Speed Up Web Apps Caching is a simple idea with big results. When you store copies of responses, users get faster pages and your servers handle fewer repeated requests. The trick is to cache wisely: different layers, different data, and clear rules for when to refresh. Caching works best when you balance freshness and speed. Static assets like images and scripts can live longer in caches, while frequently changing data needs shorter lifetimes or smart revalidation. The goal is to serve correct content without repeating heavy work on every request. ...

Caching Strategies for High-Performance Web Apps Caching is a core tool to speed up web apps. It reduces latency, lowers server load, and improves resilience. A good strategy uses multiple layers: the browser, a content delivery network (CDN) at the edge, and the origin server. When each layer is configured well, users see fast pages even during traffic spikes. Browser caching and validation The browser can serve many resources directly if they are marked as cacheable. Use clear Cache-Control headers and a sensible max-age. Public is appropriate for static assets, while private can protect personal data. Include a validator like ETag or Last-Modified so the browser can check if content changed without downloading everything again. Small, immutable assets should be served with long TTLs to maximize reuse. ...
