Enable and configure Origin shielding

What is Origin shielding?

Origin shielding is a Gcore CDN paid option that helps protect your origin server from being overloaded with requests from multiple CDN servers. This option accumulates all CDN server requests at a special server called a shield or precache server.

The shield server works like a usual CDN server but is located between your origin server and the entire content delivery network. It receives requests, caches content, transmits files from the cache, and requests the source only if it doesn’t have the needed file in the cache. When a burst in traffic occurs, the shield server receives all the requests from CDN servers, thus protecting your server from being overloaded.
