在WebBrowser下对网页进行操作其实是一件挺轻松的事情，他可以很方便实现自定义的网站访问习惯。而WebBrowser毕竟 是对MS原生控件的封装，当我们使用C#下的WebBrowser尤其是这样，虽然他可以更方便大家去调用，但是他的方便却是牺牲了灵活性为代价的。
有一天我想使用WebBrowser获取一个网站的COOKIE，在调用Document.Cookie时，发现无法完整获取其COOKIE，百思 不得其解，这么简单的功能，WebBrowser也会秀逗。经过抓包分析，发现原来该网站对写入到用户端关键的Cookie，加入httponly
HttpOnly,其实是一个提高WEB网站应用程序安全性的一个功能，但是大家往往都把他给忽略掉了。比如在ASP.NET 2.0的web.config的配制文件里就提供这个子的设置
1 <httpCookies httpOnlyCookies="true" />
2 // ***********.NET的代码如：
3 HttpCookie myCookie = new HttpCookie("myCookie");
4 myCookie.HttpOnly = true;
5 Response.AppendCookie(myCookie);
2 // ***********.NET的代码如：
3 HttpCookie myCookie = new HttpCookie("myCookie");
4 myCookie.HttpOnly = true;
5 Response.AppendCookie(myCookie);
就是这个小小的设置，令WebBrowser拿他却是没辙，查了大量资料，要想实现这个功能，一定需要实现对最原始的网络流的读写，这种方法对很多程序员来说实现难度太大了。下面就教大家实现一个很简单的实现方法
1 public string Cookie()
