摘要:
Content retrieval techniques are described. In an implementation, a determination is made as to whether a client is permitted to receive content requested by the client. When the client is permitted to receive the content, a communication is formed to be communicated via a wide area network that includes a hash list having a hash of each of a plurality of blocks of the content, each hash being configured to enable the client to locate a corresponding one of the blocks of the content via a local area network.
