摘要： 讨论了Web缓存的一般工作原理,描述了Web对象可缓存性的判断方法。为减少不可缓存对象对系统效率的影响,提出了Web缓存技术的加速方案。对于不可缓存的Web对象的请求,直接发给相应的Web服务器,而不通过代理服务器转发,系统的效率可以得到一定程度的提高。

Abstract: This paper discusses the general rules of Web caching and describes the methods of judging the cachability of Web objects.It inappropriate for the working mechanism to send requests of uncachable objects to the proxy.Solutions to the problem are presented that HTT requests can be sent directly to the Web server instead of through a proxy for the uncachable objects.By this means,the performance of the cach can be improved to some extent.
