Refers to the server(s) where content served via the CDN is stored. There are two types of origin servers, which are CDN and customer origin servers. All requests that cannot be fulfilled directly by an edge server are forwarded to an origin server. For example, a request for content that has not been previously cached is forwarded from an edge server to an origin server.
-
This feature provides a layer of protection for a customer origin server by creating an intermediate caching layer between it and our edge servers. This caching layer resides on one or more of our point-of-presence (POPs). Requests that have not been previously cached on a POP will be channelled through the closest origin shield server. The origin shield server will then either serve a cached version of the requested content or retrieve it from a customer origin server. This feature shifts the network load from the customer origin server to the CDN, since most requests will be handled by the origin shield server.
