代码说明：

Firepass - 一种隧道技术工具，通过它可以避开防火墙的规则约束，将数据流封装在合法的HTTP POST请求中。任何基于TCP/UDP协议的子协议可以通过它来穿越HTTP代理服务器对HTTP协议的严格审查。到目前为止，客户端和服务器端仅用PERL语言编写。服务器端作为一个CGI脚本运行在WEB服务器上。Firepass的主要特点是用户可以在外网使用几种方法安装服务器端脚本。用户无需在外网计算机上帮定任何端口。当服务端脚本被置于企业WEB服务器上，客户端脚本从外部网络和它通信时，Firepass也可适用于反弹作业。-Firepass-a tunnel technology tools, it can be avoided through the firewall rules to the data flow Packaging legitimate HTTP POST request.
