摘要： 构建了一种基于混合索引的浏览器缓存协作系统，它充分利用客户端浏览器缓存的内容，以P2P方式交换Web Cache，克服了集中式代理服务器存在的一些问题。客户端的Internet访问响应时间是系统设计的主要依据。索引技术是系统中影响响应时间的关键技术，为了提高响应时间，对索引技术进行了讨论，并针对该应用的特点进行了改进。系统具有以下优点：易于扩展，网络资源开销小，响应时间短，索引更新及时。

Abstract: In this paper, a Web browser cache collaboration system is built based on hybird index method in hybrid P2P network. By fully utilizing the cached pages stored in Web browser and exchanging cached pages, the system avoids the scalability problem of traditional proxy system. The main propose of the system is reducing the Internet accessing latency in large scale Intranet. The index technology, which is the key component affects the latency, is revised for this system in order to get better efficiency. The system has the following traits: scalability, low network cost, low latency, index updating in time.
