title: cross domain event source
body: <p>I am trying to create an EventSource server using nodejs, that will server requests cross domain. I am sending back Access-Control-Allow-Origin header, but the browser (nor Chrome or Opera) won`t let me connect. There are the headers I send back:</p>
  
  <pre><code>this._response.writeHead(200, {
      'Content-Type': 'text/event-stream',
      'Cache-Control': 'no-cache',
      'Connection': 'keep-alive',
      'Access-Control-Allow-Origin': '*',
      'Access-Control-Allow-Credentials': 'true'
  });
  </code></pre>
  
  <p>How can I do this the right way?</p>
  
  <p>Regards</p>
