Edge-Nodes

CDN optimization for global audiences A global audience means your site must reach users quickly, no matter where they are. A well-tuned CDN serves assets from edge locations near visitors, reducing latency and easing traffic spikes. Cache strategy Cache is the heartbeat of a fast site. Use long max-age for versioned static files and a clear rule for HTML. Fingerprinted filenames help avoid cache busting with query strings. Set Cache-Control: public, max-age=31536000, immutable for static assets; use s-maxage for shared caches. When assets update, bump the versioned name and purge the edge as needed. If supported, consider stale-while-revalidate to serve fresh content while updates load. ...

Global CDNs: Reducing Latency Across Borders Global CDNs place many edge servers around the world. When a user requests a file, the CDN serves it from the closest point of presence (PoP) rather than reaching back to the origin. This edge caching brings content nearer to people and usually shortens the time to first byte and the overall page load. With a broad network, a site feels fast in Europe, North America, and parts of Asia, even during busy periods. ...
