title: What exactly is the sAjaxSource parameter in datatables?
body: <p>According to <a href="https://datatables.net/usage/server-side" rel="nofollow">datatables website</a>,</p>
  
  <blockquote>
    <p><strong>sAjaxSource</strong> <br>
    You can instruct DataTables to load data from an external source using this parameter (use aData if you want to pass data in you already have). Simply provide a url a JSON object can be obtained from. This object must include the parameter 'aaData' which is the data source for the table.</p>
  </blockquote>
  
  <p>Now, to me (an amateur with Ajax and JSON), this is gibberish.</p>
  
  <p>I want my datatable to paginate, and load new entries using Ajax each time the table is re-sorted or the next page is chosen (instead of loading all entries up front)</p>
  
  <p>Apparently this  "url a JSON object can be obtained from" is needed if I want to set the <code>bServerSide</code> option to true</p>
  
  <p>Is there anyone that can explain this concept to me?</p>
