Origin Shield - Extra CDN Caching Layer
KeyCDN is excited to provide the Origin Shield feature for free to all customers. This extra caching layer reduces the load on your origin server and accelerates the distribution of your content from the origin server to our edge servers. The shield servers are highly redundant and automatically select the optimal location using our geolocation technology. How Does Origin Shield Work? When a client requests content from your website and that content has never been cached by any of KeyCDN’s edge servers, this is what happens with that request when Origin Shield is enabled: Requests don’t come from our growing number of edge servers but are filtered through selected shield servers.
