As a result of the drive of information diversity and the trend of personalization, more and more dynamicpages constitute the contents in the Internet. However, it is difficult to cache the dynamic Web pages because of theirdynamic characteristic. In this paper, we propose a technology to solve this problem. It isolates the static and dynam-ic contents of the page, and stores the original page of the Web server and the information of the background data-base locally, in order to improve the client's response time. Additionally, this technology also adopts correspondingreplacement algorithm and coherency policy to track the original page and the data-base update, which tries to syn-chronize the changes of the dynamic pages in time.
