Abstract

Content delivery technology, in which a request to download a content file to a downloader device is received from a remote device and the downloader device associated with the received request is identified. Address information for the content file associated with the received request is determined and a communication session is established with the downloader device based on the identification of the downloader device associated with the received request. The determined address information for the content file is sent to the downloader device over the established communication session, thereby enabling the downloader device to download the content file associated with the request.
