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
}

- HTML code
<html>
<head><title></title>
<script type="text/javascript" >
function HTTPGet()
{
var request=new ActiveXObject("MSXML2.XMLHTTP.3.0");
//...
}
</script>
<head>
<body>
<input type="textarea" id="textarea1"></textarea>
<input type="textarea" id="textarea2"></textarea>
<input type="button" id="button1" value="get" onclick="HTTPGet();" />
</body>
</html>
get送出去后没反应。纠结，脑子里乱了。
各位大侠前辈们，谁能给个最简单的交互式Web服务器，带CGI的。
链接也可以，最好能麻烦您顺手写一个。
附上我的源代码，您可以在上面修改。
