1。如何自己搞定HTTP协议

WebForm，可以重头老老实实的用ASPNET来做，不过，现在Oracle，MongoDB这样的数据库都支持本地的浏览器方式管理了，这样的应用，不用安装ASP，PHP这样的服务器，完全自己实现一个简单的HTTP服务器。

OK，我们也实现一个吧，侦听13000（这里随便什么都可以的，不过推荐使用10000以上的端口号）端口，开启多线程，做HTTP服务吧。

public void Start()
        {
            TcpListener server = null;
            try
            {
                // Set the TcpListener on port 13000.
                Int32 port = 13000;
                IPAddress localAddr = IPAddress.Parse("127.0.0.1");

// TcpListener server = new TcpListener(port);
                server = new TcpListener(localAddr, port);

// Start listening for client requests.
                server.Start();

// Enter the listening loop.
                while (true)
                {
                    ///对于每个请求创建一个线程，线程的参数是TcpClient对象
                    TcpClient client = server.AcceptTcpClient();
                    OutputLog("[Init]" + DateTime.Now + "Connected!", 0);
                    ParameterizedThreadStart ParStart = new ParameterizedThreadStart(ProcessFun);
                    Thread t = new Thread(ParStart);
                    t.Start(client);
                }
            }
            catch (SocketException e)
            {
                OutputLog("SocketException: " + e, 0);
            }
            finally
            {
                // Stop listening for new clients.
                server.Stop();
                server = null;
            }

}

        {
