C#在Windows窗体或控制台上使用HttpListener和Request.ServerVar

>项目必须请求并接收代理ServerVariables以在客户端显示.
>解析IPAddress并返回匿名状态.
>实施基本的教学方案.
>项目不得使用脚本来实现功能(例如)PHP,Perl,Asp等.
>多平台兼容(可能)

问题：

>是否可以在本地Windows或控制台应用程序上使用Request.ServerVariables,还是特定于ASP？
>如果此方法是ASP特定的,还有另一种方法从浏览器会话请求ServerVariables吗？
>如果上述方法可行,那么实现此功能的正确方法是什么？
>这里验证/设置基本认证方案的好例子是什么？喜欢设置密码和使用的用户等.
