会C，JavaScript的大侠，编写最简单的交互式Web服务器，求助！
现在在做Web server ，再看领导给我的C代码，公司领导让我添加页面，我做到了，但是源代码里有很多函数，我搞不明白流程。
是个控制台的程序，我想自己实现一个最简单的Web Server,必须具备点击按钮后，送到服务器，服务器接受到后再送回来，显示在我的页面上。我已经写了个最简单的，但功能不能达到我的要求。
我的程序一运行，第一次可以在浏览器上看到一个页面，但是点击按钮后get发送出去，并没有被服务器正确处理。
recv被阻塞，等待一会后返回 -1,查看WSAGetLastError 说：远程软件关闭连接，看来是 ie 这边关闭了。
失败了。
WSAStartup //大致步骤如下
socket
bind
listen
accept
while(1)
{
recv
send
}
