在网络程序设计过程中，我们经常要与各种类型的代理服务器打交道，比如在企业内部网通过代理去访问Internet网上的服务器等等，一般代理服务器支持几种常见的代理协议标准，如Socks4,Socks5,Http代理，其中Socks5需要用户验证，代理相对复杂。我在查阅RFC文档和相关资料后，特总结一些TCP协议穿透代理服务器的程序片断，希望对大家有所帮助。-Procedures in the network design process, we often must deal with various types of proxy servers, such as in-house CNC had agents to visit Internet web server, etc., generally a proxy server to support several common proxy protocol standards, such as socks4 , Socks5, Http proxy, Socks5 which requires a user authentication, Deputy relatively complex. I have access to the relevant RFC documents and information, special summing up a number of TCP protocol procedures penetration clips proxy server, and they hope to be helpful to everyone.
