SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This guide helps engineers design and implement multi-layer caching across CDN, browser, server, and database to reduce latency, lower server load, and improve resilience.

Core Features & Use Cases

Multi-layer caching strategy spanning browser, CDN, server, and database
ETag-based revalidation and HTTP cache-control optimization
Cache invalidation patterns including time-based TTL, on-demand, and stale-while-revalidate
CDN purging and cache-key configuration to avoid data leakage and cache-poisoning
Server-side caching with Redis and in-memory strategies for hot data
Observability: monitoring cache hit rates and purge events

Quick Start

Implement a multi-layer cache by enabling CDN caching, configuring Cache-Control and ETag, and turning on Redis-backed server cache.

FAQPage Schema

How do I implement multi-layer caching to reduce latency for dynamic data?▼

Multi-layer caching reduces latency by storing data across CDN, browser, server, and database layers. You configure TTL-based invalidation, ETag revalidation, and Redis for hot data to serve dynamic content efficiently.

What is the best way to handle cache invalidation without serving stale content?▼

Cache invalidation prevents stale content by combining time-based TTL, on-demand purges, and stale-while-revalidate patterns. This ensures users receive fresh data while maintaining high cache hit rates during background updates.

How does ETag-based revalidation work with HTTP cache-control headers?▼

ETag revalidation works with HTTP cache-control by assigning a unique identifier to responses. When the cache expires, the client sends the ETag to verify if the resource changed, downloading only if the server returns a new representation.

Can I use Redis for server-side caching alongside a CDN?▼

Yes, Redis works alongside a CDN by handling server-side caching for hot dynamic data. While the CDN caches static assets closer to users, Redis reduces database load by storing computed results and session data in memory.

How do I configure CDN purge workflows to avoid cache-poisoning?▼

Configuring CDN purge workflows prevents cache-poisoning by defining strict cache-key rules and validating purge requests. You must ensure cache-keys include necessary request variations to isolate users and avoid cross-contamination of cached responses.

Why do I need to monitor cache hit rates and purge events?▼

Monitoring cache hit rates and purge events is necessary to evaluate cache effectiveness and identify invalidation failures. Observability helps tune TTL values and ensures CDN directives actually reduce server load as intended.
