内容简介
在World Wide Web上，速度和效率是至关重要的因素。用户没有耐心来等待慢条斯理地显示Web网页，而网络管理员也在想方设法地利用带宽。正确设计的Web缓存会减少网络通信量，并加快对流行的Web站点的访问时间——对网络管理员和Web用户都是一种实惠。本书为读者提供了设计、部署和操作有效的Web缓存服务所需要的全部技术信息。它从Web缓存的工作原理的基本内容开始，从支配高速缓存能力的HTTP题头，一直讲到缓存的验证和替换算法。 本书涉及的主题包括： ·设计有效的缓存解决方案 ·配置Web测览器以使用缓存 ·设置一个能够互相通信的缓存集合 ·配置拦截缓存或代理 ·监视或微调缓存的性能 ·配置Web服务器以便与Web缓存协作 ·评估缓存产品的性能 本书也讲述了Web缓存在政策方面的重要问题，包括隐私、智能属性和安全问题。Internet服务提供商、大型公司和教育机构——简而言之，为各种各样的用户提供连接的所有网络——都能够从运行正确配置的Web缓存服务中获得巨大的利益。本书将讲述怎样正确地完成这项工作。
