Abstract Verification of the usefulness of the data distribution method by browser cache sharing Yusei Irifuku In recent years, delivery and acquisition traffic of large-volume contents such as video contents are increasing rapidly with the spread of development of video contents, a mobile terminal and the broadband connection environment.load concentration to a server is a problem depends on traffic increase.p2p Web Proxy exists as the existence technology to settle the problem.p2p Web Proxy is to use a client/server type communication and the P2P type communication which are a conventional delivery system, and the method which disperses traffic.but for after download of contents also to maintain cash in P2PWebProxy of existence, the problem that a memory space and an upload communication band are consumed exists.only during communicating, the cooperation type P2PWebProxy which settles a problem by sharing cash is proposed.and I estimate more than the client server type communication which is a conventional delivery system about a load of a server, and the validity of the proposition system is indicated. key words Web P2P WebProxy ii
