使用c#实现简易的http传输

public partial class Form1 : Form
    {
        static Socket _socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);  //侦听socket

        public Form1()

        }

        {
            string c = CookieReader.GetCookie("http://10.33.208.230/uac/");
            this.textBox1.Text = c;
            Program.cookie = c;
            this.Text = "服务端:" + webBrowser1.Document.Title;
        }

        private void Form1_Shown(object sender, EventArgs e)
        {
            _socket.Bind(new IPEndPoint(IPAddress.Any, 8123));
            _socket.Listen(100);
            _socket.BeginAccept(new AsyncCallback(OnAccept), _socket);
        }

        /// 

        /// 接受处理http的请求
        /// 
        /// 
        static void OnAccept(IAsyncResult ar)
        {

                //NO.1  并行处理http请求
                socket.BeginAccept(new AsyncCallback(OnAccept), socket); //开始下一次http请求接收   （此行代码放在NO.2处时，就是串行处理http请求，前一次处理过程会阻塞下一次请求处理）

                //NO.2  串行处理http请求
            }
            catch (Exception ex)
            {
                //writeLog("处理http请求时出现异常！" + Environment.NewLine + "\t" + ex.Message);
            }
        }

        static void sendPageContent(byte[] pageContent, Socket response)
