Global Content Delivery (CDN) Purge Logic

This skill focuses on the balance between high-cache-hit rates and fresh data delivery.

Instructions

1. Set up 'Surrogate Keys' or 'Tags' for granular cache invalidation.
2. Implement 'Atomic Purging' to ensure related assets are cleared together.
3. Optimize Cache-Control headers (max-age, s-maxage, stale-while-revalidate).
4. Monitor CDN logs to identify 'Cache Misses' and optimize hit rates.
5. Design failover patterns between multiple CDN providers.

Examples

• "Configure a Cloudflare cache purge trigger for a specific blog post update."
• "Optimize cache headers for a global e-commerce product catalog."
