title: Best content type to serve JSONP?
body: <p>I have a webservice that when called without specifying a callback will return a JSON string using <code>application/json</code> as the content type.</p>
  
  <p>When a callback is specified it will wrap the JSON string in a callback function, so it's not really valid JSON anymore. My question is, should I serve it as <code>application/javascript</code> in this case or still use <code>application/json</code>?</p>
