重定向代理(简单的页面重定向）

老大有个需求根据流量和负载分流定向页面，重定向可简单用http，302来实现 

 

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.InetSocketAddress;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.SocketAddress;

public class Direction ...{

    /** *//**
     * @param args
     */
    public static void main(String[] args) throws Exception ...{
        // TODO Auto-generated method stub
        ServerSocket ss = new ServerSocket();
        InetSocketAddress sa = new InetSocketAddress(80);
        ss.bind(sa);
        while(true)...{
            Socket socket = ss.accept();
            BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            PrintWriter out = new PrintWriter(socket.getOutputStream(),true); 
            String input;
            while(true)...{
                input = in.readLine();
                System.out.println(":"+input);
                if(input.equals("") || input==null)...{
                    break;
                }
            }
            out.println("HTTP/1.1 302 Found");
            out.println("Location: http://bbs.nju.edu.cn");
            out.close();
            in.close();
            socket.close();
            System.out.println("--------over------------");
        }
    }
}
