Caching for end-user systems to reduce usage of access links to a communication network

An access system that is coupled to a communication network hosts a file for an end-user system. The access system receives the file from the end-user system. The access system stores the file in a memory in the access system. The access system receives a message from the communication network, wherein the message requests the file from the end-user system. In response to the message, the access system determines if the file may be transferred to the communication network from the memory in the access system. If the file may be transferred to the communication network from the memory in the access system, then the access system notifies the end-user system that the file will be transferred from the memory in the access system to the communication network and transfers the file from the access system to the communication network.
