title: Writing to Socket outputStream w/o closing it
body: <p>I'd like to write some messages to the server.
  Each time, for the tramsmitting only, I'm closing the outputStream and reopen it when I have to send the next message.</p>
  
  <pre><code>os.write(msgBytes);
  os.write("\r\n".getBytes());
  os.flush();
  os.close();
  </code></pre>
  
  <p>How Can I keep this Socket's OutputStream, os, open and still be able to send the message?</p>
  
  <p>Thanks. </p>
