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.
