About CDNs
Content Delivery Networks (CDNs) are a network of servers distributed all over the globe that locally stores static files like images, css and javascript. When a web browser requests a locally stored file, it is able to be sent from the closest CDN server. This is faster than having to retrieve the file from the web server which may not be as geographically close. This typically results in a faster loading website.
Domains that use Sav's free Custom DNS, powered by Cloudflare, can enable a free CDN with just a few mouse clicks.
- Enable Custom DNS on your Domain and navigate to the DNS Settings Page
- Ensure Each A, AAAA and CNAME record type have "Proxy" enabled. This will route all web traffic through the Cloudflare Proxy Servers which also function as a free CDN.
If a static file changes on your web server that is not reflecting in web browser, click the Purge All button under the Purge Cache heading to have the CDN fetch new copies of all static files from the source web server.
Development Mode disables the CDN cache for 3 hours and is typically used to see changes being made to a site in real time.
