title: Simple java http client no server response
body: <p>I'm attempting to write a simple Java http client that simply prints out one line of the server response. My problem is that I get no response from the server. Here is what I have, which is compiling and running with no explicit errors, it just hangs after I type a hostname, e.g. 'www.google.com':</p>
  
  <pre><code>import java.io.*;
  import java.net.*;
  
  public class DNSTest {
      // Constructor
      public DNSTest() { }
  
      // Builds GET request, opens socket, waits for response, closes
      public static void main(String[] args) throws Exception{
          String line;
          BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
          //For each hostname
          while ((line = br.readLine()) != null){ 
              //Resolve the hostname to an IP address
              InetAddress ip = InetAddress.getByName(line);
  
              //Open socket on ip address
              Socket socket = new Socket(ip, 80);
              PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
              BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
  
              //Send request
              out.println("GET /index.html HTTP/1.0\n");
  
              //Read one line of input
              System.out.println("Response from "+line+": "+in.readLine());
  
          }
      }   
  }
  </code></pre>
  
  <p>Any suggestions? Note that this assumes an 'index.html' exists - it still just hangs even if this is true.</p>
