Systems, methods, and devices relating to data forwarding in a content delivery network are described herein. In a method, a cache server may receive a request for a first data object from a client device. The cache server may request for and receive the first data object from an origin server. The cache server may determine one or more rules, implemented at the Internet or transport layer of the cache server, configured to cause future data object(s), associated with the first data object, to be forwarded to the client device via the Internet or transport layer, as the case may be. The one or more rules may be additionally or alternatively configured to cause the future data object(s) to be sent to an application layer of the cache server for potential storage at the cache server.
