3 Abstract The data distribution system using browser cache sharing and WebRTC Kazuki Matsushita In recent years, broadband connections to the Internet environment have spread, thus traffic delivery and the retrieval of large-volume content such as videos have soared. P2P Web Proxy is present as an existing technique for solving the problem. However, it is difficult to use for client because it has two problems. It is a problem of retaining the cache after download of the content, a problem that it is necessary to open the port toward the outside. In this paper, by using technologies of browser plug-in and WebRTC to propose a system which solves the aforementioned problems. And implement as browser cache sharing system using WebRTC. key words Web, HTTP, WebRTC, P2P ii
