Implement CDN cache invalidation using purge APIs, surrogate keys, tag-based invalidation, and versioned URLs to keep content fresh

Set Cache-Control, ETag, and Last-Modified headers to control browser and CDN caching for API responses and static assets

Implement useful caching strategies for databases, APIs, and frontends using Redis, CDNs, and browser caches.

Configure content delivery networks with edge caching rules, cache invalidation, and geographic optimization for static and live content.

Deploy static files to a dedicated content delivery network or object storage to offload origin servers, reduce latency, and improve availability for assets like images, CSS, and JavaScript.

Template for defining CDN caching rules and edge behavior: cache keys, TTL by content type, query parameter handling, header forwarding, purge strategies, and origin shield configuration with code examples.

Cache GraphQL responses at every layer: CDN, gateway, DataLoader, persisted queries, and client-side. Covers cache keys, invalidation, HTTP caching directives, and Apollo Client cache.

Design CDN caching for web applications and APIs. Covers edge caching, cache keys, cache headers, invalidation strategies, surrogate keys, and multi-CDN setups for global performance.

A practical guide to caching strategies: browser caching, CDN edge caching, application caching with Redis, and database query caching. Learn when to use each and how to avoid cache invalidation nightmares.
