The class below sends a simple request for my webpage and retrieves
the response. But for some reason, the while loop seems to take
forever.
If I uncomment the System.out.print((char)c), I see the response
itself come back quickly, but the program will still stall for another
ten seconds or so, even though all of the response is retrieved.
It didn't help reading the socket with a bufferedreader (or any other
kind of reader for that sake) instead.
The API states that the read() method returns -1 at the end of the
stream, but it seems that it keeps blocking waiting for input data.
How do I get around this problem?

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.net.Socket;

public class Connection {

public static void main(String[] args) throws Exception{

Socket s = new Socket("www.stud.ntnu.no", 80);
DataOutputStream dos = new DataOutputStream(s.getOutputStream());
DataInputStream dis = new DataInputStream(s.getInputStream());
dos.writeBytes("GET /~paulsber/index.html" +
HTTP/1.1\r\nHost:www.stud.ntnu.no\r\n\r\n");
dos.flush();
           
int c = 0;
StringBuffer response = new StringBuffer();
while((c = dis.read()) != -1){
 response.append((char)c);
 //System.out.print((char)c);
}
System.out.println(response);
}

}
