ABSTRACT:
A method, system, and computer readable medium for delivering media object to a user over a computer network. Media object is divided into first portions and remaining portions, and the first portions are stored on edge server computers in communication with client computers. Upon receiving a request for delivery from a user, the edge server computer transmits the first portion of the media object to the client computer. The edge server computer then requests delivery of the remaining portion of the media object from the origin server computer. Upon receipt of the remaining portion of the media object from the origin server computer, the edge server computer transmits the remaining portion of the media object to the user such that delivery of both portions of the media object to the client computer is continuous and uninterrupted.
