Topics

CDN Caching

Part of the Backend Developer Roadmap.

Summary

Caching static or semi-static responses at edge servers geographically close to users, so requests never have to reach your origin server at all.

How to Learn This

  • 1Check the `Cache-Control` headers your API sends for cacheable responses.
  • 2Learn how a CDN decides whether to cache a response based on headers.
  • 3Understand which endpoints are safe to CDN-cache (public, non-personalized data) and which aren't.
