title: Bidirectional communication with Node.js
body: <p>I'd like to send JSON data from the client to my Node.js server via jQuery and Ajax (websockets not possible) and get a JSON response back. I'd do that via POST, but since the Node.js server is running separately from the Apache server (which delivers my client-side website), jQuery is falling back to GET messages due to the same-origin-policy.</p>
  
  <p>What's the best way to fix that?</p>
