摘要

分块缓存技术能够有效提高动态网页的服务质量.现有的既存系统较少使用分块缓存技术设计

如何将其应用于这些系统是一个很大的挑战.本文提出了一种在线的动态网页分块缓存方法

使原系统演化成基于分块的系统

为用户服务.该方法具有三方面优点:(1)使原系统在线演化

不影响系统对用户的服务提供;(2)简化了模板的维护

使逻辑执行的粒度从页面降低到分块

减轻了服务器端的压力;(3)独立于原系统

有效支持系统的变化和升级.文章最后对方法进行了实现和评估

结果说明该方法能够较好实现系统的演化

提高系统的服务质量.

Abstract

Fragment-based caching technology can effectively improve the quality of dynamic web pages' services.Nowadays

many existing dynamic web pages systems have not been designed by this technology

so how to apply it to these systems is a big challenge.This paper presents an online approach to apply fragment-based caching technology to these existing systems.Our approach has three main advantages as follow.Firstly

the original system is evolved into a fragment-based system online without service interception.Secondly

the approach simplifies templates maintenance

decreases the logic computing granularity from page to fragment

and greatly reduced the pressure on the server side.Thirdly

the approach is independent of the original system

which effectively supports the change and upgrade of the system.Evaluation results show that this approach can fulfill the system evolution and greatly improve its service quality.
