用socket抓取网页建立连接后如何复用同一个socket?

以下是程序
只能抓取前面一个网页后面复用的不行

public class text
{
public static void main(String[] args) throws IOException
{
String hostname = "www.javaeye.com";
int port = 80;
InetAddress addr = InetAddress.getByName(hostname);
System.out.println(addr);
Socket s = new Socket(hostname, port);
// s.setSoTimeout(99999);
s.setKeepAlive(true);
if(s.getKeepAlive())
{
System.out.println("******************keep-alive*****************");
}
BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
wr.write("GET / HTTP/1.1" + "\r\n" + "Host: www.javaeye.com" + "\r\n" + "Connection: Keep-Alive" + "User-Agent: tse" + "\r\n");
wr.write("\r\n");
wr.flush();
BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
String line;
while((line = br.readLine()) != null)
{
System.out.println(line);
}
System.out.println(s.isClosed());

//以下想用复用同一个HOST＋port的socket,可是不行
wr.write("GET /search HTTP/1.0" + "\r\n" + "Host: www.javaeye.com" + "\r\n" + "Connection: Keep-Alive" + "User-Agent: tse" + "\r\n");
// wr.write("GET /");
// wr.write("HOST:" + hostname + "\r\n");
wr.write("\r\n");
wr.flush();
BufferedReader b = new BufferedReader(new InputStreamReader(s.getInputStream()));
String linee;
if(s.getInputStream().available()  > 0)
{
System.out.println("hava something");
}
while((linee = b.readLine()) != null)
{
System.out.println(linee);
}
}
}
