How 2 pass a request from a broswer to remote server via a proxy server

Question

hi my program is on a proxy server it will be lisenting in port 9876
i have configured in a way that all browsers request pass thro this proxy server
so when user request for www.yahoo.com in the browser the
resquest is passed 2 this proxy server. so i got the host name and created a socket.
i read all the request that has come from the browser such as "GET www.yahoo.com HTTP/1.1 ,,"
I got the outputstream for the remote socket and i passed all these request to the remote host.. but i could nt get any response frm server can any one help me out?

ServerSocket ser;
Socket myclient;
BufferedReader br;
String cf1="\r\n",cf2="\r\n\n",lf="\n";
OutputStream o_remote;
public Proxyserver()
try
ser=new ServerSocket(9876);
myclient=ser.accept();
// read inital requst from browser
br=new BufferedReader(new InputStreamReader(myclient.getInputStream()));
String req=br.readLine();
String temp=req;
int val=temp.indexOf((int)'/',11);
String host=req.substring(11,val);
//connect 2 host
Socket remote=new Socket(host,80);
System.out.println(remote.toString());
o_remote=remote.getOutputStream();
while(req!=null)
System.out.println(req);
o_remote.write(req.getBytes(),0, req.length());
o_remote.write(cf2.getBytes());
o_remote.flush();
req=br.readLine();
o_remote.write(lf.getBytes());
o_remote.write(lf.getBytes());
o_remote.flush();
// wait for response from remote server
InputStream in=remote.getInputStream();
int response=in.read();
while(response!=-1)
System.out.println((char)response);
response=in.read();
//close all sockets
remote.close();
myclient.close();
ser.close();
}catch(Exception e){}
public static void main(String a[])
new Proxyserver();
