Understanding the Rocket.net CDN (Content Delivery Network)

What is a CDN?

A CDN (Content Delivery Network) is a global delivery network. Our CDN at Rocket.net is provided by Cloudflare on the Enterprise tier (a $6,000+ value).

At Rocket.net, we use the Cloudflare CDN to deliver entire WordPress sites in 250+ locations around the globe. Rather than having a caching mechanism on the server your WordPress is installed on, we leverage Cloudflare’s global network to place your website as close as possible to your visitors.

How to leverage the Rocket.net CDN

At Rocket.net, the Enterprise CDN is enabled by default and there is no need to manage any of the configuration. All Rocket URLs (*.onrocket.site) and custom domains route through the CDN by default.

What does the CDN cache?

Our CDN caches all static assets (including HTML) by default. Dynamic requests such as admin-ajax.php, wp-login.php, and so on are already configured to bypass the cache due to our “bypass-the-cache” functionality for WordPress cookies.

WooCommerce stores can also benefit from our CDN. WooCommerce content is delivered from the cache until a user starts interacting with the store and becomes a dynamic user. Dynamic users still receive all static assets such as images, CSS, and JavaScript from the cache. This means that your WooCommerce site experiences a lighter load, thereby increasing the number of users who can shop simultaneously.
