What’s the best cdn strategy for global edge-caching performance?

Asked on Sep 25, 2025

Answer

For optimal global edge-caching performance, a CDN strategy should focus on reducing latency by caching content close to users and efficiently managing cache expiration. This involves setting appropriate cache headers and utilizing CDN features like cache purging and dynamic content caching.

Example Concept: A robust CDN strategy leverages geographically distributed edge servers to cache static assets such as images, CSS, and JavaScript files closer to end-users. By setting cache-control headers like "max-age" and "s-maxage," you can control how long content is cached at the edge. Additionally, using features like cache purging allows you to update content globally without delay, ensuring users always receive the most current version.

Additional Comment:

Ensure your CDN supports HTTP/2 or HTTP/3 to improve connection efficiency.
Use "stale-while-revalidate" to serve stale content while fetching updates in the background.
Implement cache purging strategies to update content without waiting for cache expiration.
Consider using a multi-CDN approach for redundancy and improved global reach.
