The Research Of Some Key Technologies Based On Web Application

With the rapid development of Internet,web application has existed all walks of life,from business,banks,financial institutions,entertainment,education to government agencies.Web make profound influences on our daily lives.Because of the abundant user interface and favorable maintainability it provided,web application has become more and more popular in Enterprise Informatization.People increasingly expect on response time and service performance.Through key technologies,improving service performance and user experience become important research direction.Actually,the key technologies directly affect web applications,through the whole chain which from client,network to server.Each weak part of the entire chain will lead to the poor performance and the terrible user experience.Because of partially focusing on problem-solving,the traditional solutions make tremendous efforts with little success.In fact,it is a systematic and all-around study.Only pay more attention on various aspects of the entire chain(client→network→server)can we fundamentally resolve the problem.Start with three parts which affect web performance.Fistly,in the aspect of network,make a research on the application of vpn in enterprise networking.Design a network based on SSL vpn in accordance with the requirements of the enterprise, which helps interconnection of enterprise branches.The system supports two-way SSL authentication to ensure system security.Secondly,the research on WebLogic Server is made in regard of server.Through monitor from WebLogic Server Administration Console(WLS Administration Console),a number of principles can be followed for optimizing system.The implementation steps can be summed up in the process of movement from Tomcat to WebLogic Server.Finally,make a research on cache and AJAX in terms of development technology. AJAX will be used in client development to improve user experience and integration solution of cache is proposed,which integrate OSCache into Ehcache.The overall-optimization thinking about web application is presented.The joint use of key technologies finds a way to enhance server performance,which affects web performance.Apply this thinking to practice-the second phase project of the Yangtze River Waterway to obtain better service performance and better user experience.
