ABSTRACT:
A repeater server in a content delivery network (CDN) maintains a list of resources that are no longer valid. When the server gets a request for a resource, it checks whether that resource is on the list, and, if so, it replicates the resource from a content provider's content source such as an origin server. Otherwise the repeater server tries to serve a copy of the requested resource or to obtain a copy from another location in the CDN.
