Caching Strategies
Last updated
What is Caching Strategies?
Cloudflare Workers allow fine-grained control over caching. You can use the Cache API to store and retrieve responses directly within your Worker, bypassing the origin server. Strategies include:
- Cache-First: Serve from cache if available, otherwise fetch from origin.
- Network-First: Always fetch from origin, caching the response for subsequent requests.
- Stale-While-Revalidate: Serve from cache immediately, then update the cache in the background.
You can also manipulate HTTP cache headers (Cache-Control, Expires) to control how Cloudflare's CDN caches content. Effective caching is critical for improving performance and reducing origin server load.
