//Try the following code:
//It works in all cases (as long as the client is not //hid beneath a or proxy).
import java.net.*;
import java.io.*;
public class webClient {
     public static void main(String args[]) {
          try{
               if(args.length < 1) {
                    System.out.println("webClient URL");
                    System.exit(0);
               URL u = new URL(args[0]);
               BufferedInputStream inputStream = new BufferedInputStream((u.openConnection()).getInputStream());
               int n;
               byte[] buff = new byte[2048];
               ByteArrayOutputStream out = new ByteArrayOutputStream();
               while((n = inputStream.read(buff)) >= 0)
                    out.write(buff, 0, n);
               System.out.println(out.toString());
          } catch(Exception e) {
               e.printStackTrace();
}
