Web application servers are rapidly becoming the essential resources for competitive advantage, because e-businesses can gain amount of revenues. However, benefits are coming from consumers, more consumers cause more benefits. So web application server, which can provide more efficient services, will attract more people. To gain the biggest advantage, we research in Internet to find out a new method. A web application server means it will have frequent transactions. And it will access data in database and produce new web pages to respond consumers through the CGI (Common Gateway Interface) programs. In this paper, we present a new method that can improve performance of web application server through saving network¡¦s bandwidth, reducing web server loading and cutting wait-time of end user. The method primarily uses divided dedicated data and common information of the source web page. With saving the multiple download time of the common information, the efficiency of network¡¦s bandwidth and the user waiting time can be improved effectively. The method also can be easily combined with other existed technologies that can solve Internet efficiency problems. And we developed an approach to design and implement an efficient web application server. Finally, we measure the result of the traditional method and the new method to prove that our method really can save network¡¦s bandwidth, reduce web server loading and cut wait-time of end user. We hope the method can improve general existed problems in Internet.
