Based On The Ajax Server-side Control Theory (scba) Development And Use

With the fast development of Internet, the Web users' demands are greatly increased. Web applications have not only been a platform displaying information simply any more. Instead, it will introduce the core business logical rules and become a business management platform in IT field step by step. Moreover, the Web applications have a vast number of users. If there are too many concurrent users, the site would react more and more slowly. And this would not satisfy the users. It can speed up the reaction of website by increasing bandwidth. But this would arise the expense of users. Therefore, applying new technologies to improve the speed of web application's reaction is becoming a great topic of today.In this paper, we delve into the critical theory of Ajax (Asynchronous JavaScript and XML), which is one of the core technologies of Web 2.0. Referred to the technology of controls provided by .NET IDE (Integrated Development Environment), we propose a method to improve the speed of website's reaction. We design and implement a set of SCBA (Server controls based on Ajax theory) controls as well. As expected, the method can decrease the requests from clients to servers in a certain degree. So it makes the partial refreshing of websites come true and improves the reaction speed of sites.We take experiments on SCBA and traditional .NET standard controls. The result shows that SCBA controls can improve the speed of site's reaction more obviously. It's more convenient for the designers to develop the websites with SCBA controls. And it also helps to improve the efficiency of developing partial refreshing websites.
