title: Jquery Datatables return additional information from server
body: <p>using JQuery Datatables and all is going well. </p>
  
  <p>I've worked out how to send addtional information from the client to the server. Now, I want to go back the other way.</p>
  
  <p>So, how do I send extra information from the server to the client. I would have thought I could add an extra entry in the returned JSON and pull it out somewhere. One item I'd perhaps like to send back is how long the server took to handle the response. I can then show this information to the user.</p>
  
  <p>Any help would be much appreciated. Thanks</p>
