Abstract
In the described embodiments, local caching servers (LCSs) are configured to cache content so that the content can be acquired by client electronic devices that are located on local area networks (LANs) with the LCSs. In some embodiments, to enable the acquisition of the cached content, a client electronic device sends, to a registration server, a request for identifiers for LCSs that are located on a LAN with the client electronic device. The request includes one or more “listen ranges,” each of which includes an indication of client electronic devices for which a corresponding LCS is to provide content. The registration server uses the listen ranges to select one or more LCSs, and returns identifiers for the one or more LCSs to the client electronic device. Using the one or more identifiers, the client electronic device acquires the content from an LCS via the LAN.
