今天早上 我写了一篇 用socket 做的 时间服务器，当时我说准备用一段时间作个不需要客户端接收数据

而是用 浏览器 接收数据的程序，很顺利，一天的时间 我就做好了：）

闲话不说，先看程序。。。

using System;
using System.Collections;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Threading;

class HttpProcessor
{
    private Socket s;
    private BufferedStream bs;
    private StreamReader sr;
    private StreamWriter sw;
    private String method;
    private String url;
    private String protocol;
    private Hashtable hashTable;

    public HttpProcessor(Socket s)
    {
        this.s = s;
        hashTable = new Hashtable();
    }

    public void process()
    {
        NetworkStream ns = new NetworkStream(s, FileAccess.ReadWrite);
        bs = new BufferedStream(ns);
        sr = new StreamReader(bs);
        sw = new StreamWriter(bs);
        writeURL();
        s.Shutdown(SocketShutdown.SdBoth);
        ns.Close();
    }
    
    public void writeURL()
    {
        try
        {
            writeSuccess();
        }
        catch (FileNotFoundException)
        {
            writeFailure();
            sw.WriteLine("File not found: " + url);
        }
        sw.Flush();
    }

    public void writeSuccess()
    {
        sw.WriteLine("HTTP/1.1 200 OK");
        sw.WriteLine("Server: Microsoft-IIS/5.0");
        sw.WriteLine("Date: Mon, 27 Nov 2000 08:19:43 GMT");
        sw.WriteLine("Content-Length: 6");
        sw.WriteLine("Content-Type: text/html");
        sw.WriteLine("");

        String strDateLine;
        DateTime now;
        now = DateTime.Now;
        strDateLine = now.ToShortDateString() + " " + now.ToLongTimeString();
        sw.WriteLine(strDateLine);
    }

    public void writeFailure()
    {
        sw.WriteLine("HTTP/1.0 404 File not found");
        sw.WriteLine("Connection: close");
        sw.WriteLine();
    }
}

public class HttpServer

        }
    }
    public static int Main(String[] args)
    {

        if (args.GetLength(0) > 0)

        else

        }
