Adaptive, Personal Localized Cache Control Server

A server may be configured to receive an indication that a first user device stores a particular content item; receive, from a second user device, a request for content; and determine that the requested content is available from the first user device. The determining may include determining that the particular content item stored by the first user device corresponds to the request for content, and determining that a local peer connection is available between the first user device and the second user device. The server may further output, to the first user device, an instruction to output the requested content to the second user device via the local peer connection, and/or the server may output, to the second user device, information which may allow the second user device to request the content from the first user device via a local peer connection.
