代理服务器特性探测技术研究

Research on probing characteristics of proxy server

从用户角度远程探测代理服务器的通信特性。对代理的功能及分类进行总结,提出了代理服务器工作模型,对其逻辑模块和影响通信的因素进行分析。在此基础上分析代理特性探测原理,以HTTP代理为例设计了探测算法并实现了探测系统原型。该系统实现了Windows域环境下特定认证机制的穿透;经过测试并分析其性能,具有一定的适用性。

The communication characteristics of proxy server were investigated from the angle of remote host computer.The functions and classifications of proxy server were summarized,and its working model was proposed,together with analysis of its logic modules and factors that influenced communication.After the principle of probing characteristics of proxy server was analyzed,a probing algorithm for HTTP proxy was designed,and a probing system prototype was implemented.The system accomplished penetrating through spe...
