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.
In order to strengthen the security of WWW service in campus network, we need to realize a proxy server that can operate both efficiently and stably.Based on the detailed analysis of HTTP protocol, the advantages and disadvantages of proxy service model and common implementation methods Detailed analysis, and finally made a detailed design of pre-created WWW proxy server based on thread and implemented in Linux environment.This system has completed a series of tests, the test shows that the use of pre-created technology to improve the operation of the proxy server Efficiency.At present, the system has been running on the Internet and can provide WWW proxy services to nearly 10 departments in the campus network and schools stably, and has achieved good results and meets the needs of the campus network.
