摘要
Web对象缓存技术是一种减少web服务器访问通信量和访问延迟的重要手段。Web缓存的引入虽然大大减轻了服务器负载,降低了网络拥塞,减少了客户端访问的延迟等优点,但同时也带来缓存的一致性问题,这样使客户端获得web的数据可能不是最新的版本。该文通过分析现有的缓存一致性方针,提出了一个应适于web的强缓存一致性算法。
Web object caching technology is an important means to reduce network traffic and access latency. Although web cache can reduce the load on the server significantly, network congestion, and the latency of each cache request, it brings a question of cache consistency. That is, a stale cache might return to a client. In this paper, after analyzing the existing cache coherence, we propose a strong cache consistency that is be suitable for web appellations.
