Origin Shielding

The best way to improve delivery is to replicate the content on the edge servers. However, keeping all the content on the edge isn’t always the most efficient strategy. Mid-tier caching enables a set of rules to shield your origin from new requests.

If some of your content should expire, you can chose to preserve it at the mid-tier to be reactivated instantly. Websites and Applications with large libraries and/or high asset turnover make the most of mid-tier cache to protect their origin.
