Как правильно задать http запрос, если нужно задать reqest header?

// HTTP GET through socket, not through "URL" class
 
import java.net.*;
import java.io.*;
 
public class sget 
{
  public static void main ( String[] args ) throws IOException 
  {
    Socket s = null;
 
    try 
    {
        String host = "computing.dcu.ie";
        String file = "/~humphrys/howtomailme.html";
        int port = 80;
    
        s = new Socket(host, port);
 
        OutputStream out = s.getOutputStream();
        PrintWriter outw = new PrintWriter(out, false);
        outw.print("GET " + file + " HTTP/1.0\r\n");
        outw.print("Accept: text/plain, text/html, text/*\r\n");
        outw.print("\r\n");
        outw.flush();
 
        InputStream in = s.getInputStream();
        InputStreamReader inr = new InputStreamReader(in);
        BufferedReader br = new BufferedReader(inr);
        String line;
        while ((line = br.readLine()) != null) 
        {
                System.out.println(line);
        }
        // br.close();          // Q. Do I need this?
    } 
    catch (UnknownHostException e) {} 
    catch (IOException e) {}
 
        if (s != null)
        {
                try
                {
                        s.close();
                }
                catch ( IOException ioEx ) {}
        }
  }
}
