预创建代理服务器的分析与设计

Analysis and design of proxy server baseduon precreating technology

为了加强校园网WWW服务的安全性,需要实现一个既能稳定运行效率又比较高的代理服务器.在对HTTP协议进行详细分析的基础上,对代理服务模型和常用的实现方式的优缺点进行了详细的分析,最后对基于线程预创建WWW代理服务器做了详细的设计,并在Linux环境下加以实现.该系统已经完成了一系列的测试,测试表明采用预创建技术,提高了代理服务器的运行效率.目前该系统已经在Internet上运行,并能稳定地为校园网及学校近10个部门提供WWW代理服务,取得了良好的效果,满足了校园网的需求.

Proxy server is one of the effective ways to solve network security problem.In order to improve the security of WWW service in campus network,it's necessary to implement a stable and high efficiency proxy server.Based on the analysis of HTTP protocol,the advantages and disadvantages of proxy server model are analysed in detail and implemented under Linux.The system has completed a serial of tests and the result indicates that it runs effectively with the precreating technology.The system is providing WWW proxy service for network center and almost ten deparments of DMU now.
