Abstract
Systems and methods are described to reserve cache space of points of presence ('POPs') within a content delivery network ('CDN'). A provider may submit a request to the CDN to reserve cache space on one or more POPs for data objects designated by that provider. Thereafter, the CDN may mark those designated data objects within its cache as protected from eviction. When the CDN implements a cache eviction policy on the cache, the protected objects may be ignored for purposes of eviction, or may be evicted only after non-protected data objects.
