The Implement And Application Of The Light Weighted Web Server Model

With the rapid development of internet technology, web has been widely used and achieved great success. The web is moderately common, platform-independent and highly interactive. With the continuous development of information technology, web has been applied to varieties of fields and many currently existing applications are being moved to web. And the web server provides those applications a real-time interactive platform. Compared with commonly used web servers, light weighted web server has many advantages: less server resource required, lower maintaining cost, lower complexity, faster running speed and easier to deploy. And it has been widely applied in some specific environment.The paper research web service model deeply and design a light weighted web server to be embedded into other applications.This paper is divided into the following parts of the research and development work on the light weighted web server:First, the paper introduces the basic supporting technologies for web server: HTTP protocol and TCP/IP protocol. Also introduces the SSL protocol and its applications.Second, implements the standard HTTP protocol with socket and a C servlets container (and also called "light weighted web server") adapted JAVA servlets container specification as the supporting theories.Third, the paper introduces the appliance of SSL and make use of OpenSSL to implement transferring HTTP packets on SSL to transfer network information securely.Fourth, we tested the throughput and hit of light weighted web server on windows platform. Finally, the paper demonstrates an application of light weighted web server in Distributed Vulnerability Checking System. The application consists of a centre server,a patch server,the user agent and the web server.The components comunicate with each other through web, the light weighted web server in the process of interactive communication has played the role of a bridge, Provide a securely and reliable information transmission services.The result of testing lightweighted web server demonstrates that the server can run stably and provide service with good quality.
