The Design Plan And Realization Of Moving Web Applications From Intranet To Internet

With the development of modern enterprise and the international, more and more enterprises recognize the importance of Web applications. And With the emergence of SaaS and PaaS model of business development, enterprise Intranet Web applications moving to the Internet environment has become a direction of development.In this paper, from three aspects(compatibility,performance,safety)analysis the difference between Web applications in Internet and in Intranet.And combination with common enterprise application development platform (Universal Enterprise Application Platform, UniEAP) to carry out the actual analysis of system architecture. Analysis the problems may be encounted during the migration process. In compatibility, this paper manily analysis programming the Web page which can be showed normally in many kinds of browser and support the internationalization. UniEAP combine with Dojo framework to achieve higher compatibility page. In performance, this paper mainly focuses on reducing page load time and caching the data. From these two points to optimize system performance. This paper uses memcache and ehcache as memory cache tools on the server-side, use Google Gears as disk cache tools on the client-side. In safity, this paper mainly analysis the Web application security based on the top ten security vulnerabilities selected by OWASP. At first use AppScan to scan UniEAP platform and found four serious problems. Put forward some ways to resolve Ajax request access control and data validation on the server-side.In this paper, expounding the problems that may be encountered in the migration, and from the perspective of the Web application layer put forward some proposed solutions to solve these problems. Although these solutions are based on UniEAP business platform, for other enterprise applications, these solutions may be encountered with a certain degree of reference during migrate the platform to Internet.
