Abstract
Systems, methods, and computer-readable media provide content items to clients. In one implementation, a system stores data identifying a plurality of cache servers, the cache servers storing the content items for download by a plurality of clients. The system receives a request from a first one of the clients to download one of the content items. The system selects one or more of the cache servers for providing the requested content item to the first client. The system transmits identifiers of the selected one or more cache servers to the first client, and transmits instructions to the first client. The instructions are operable, when executed by the first client, to determine whether the selected one or more cache servers have a local copy of the requested content item. When the first client determines that a first one of the selected one or more cache servers has a local copy of the requested content item, the first client downloads the requested content item from the first selected cache server.
