- Cloudflare is a pull CDN: First request goes to your server, then is cached at that specific data center for subsequent visitors in that region. Other CDNs often offer Push CDN, which you can preload their cache.
- Cloudflare is a somewhat transparent CDN: It doesn’t use a special CDN subdomain for cached files. It’s cached in transit from your regular URLs. Cacheable (static) files are cached using their original URL, while dynamic files pipe straight through the reverse proxy.
