title: Correct syntax for a servlet that doesn't "return anything"?
body: <p>What is the correct way of terminating a servlet that doesn't return any data to the client?</p>
  
  <p>The purpose of the servlet in question is to recive some data from an Ajax request and fire off a TCP message to a piece of hardware to tell it to change it's state.</p>
  
  <p>Do you have to specify a response at all?</p>
  
  <p>I've opted for getting a reference to the Output stream and closing it, is this correct?</p>
  
  <p>Should I send back a "hey that worked" message? </p>
