Cloudflare’s CDN and caching layer is one of the platform’s greatest strengths. For static sites like Hugo, it delivers global performance with almost no configuration.

This chapter provides a calm, practical explanation of Cloudflare’s CDN architecture and the tools available for controlling cache behavior: Cache Rules, Page Rules, Transform Rules, and more.
