title: Setting `processData: false` in jQuery + Datatables appends unknown stuff to URL of my Ajax calls
body: <p>In following <strong><a href="https://stackoverflow.com/a/17216158/99971">this post</a></strong>, I wanted to convert all my Ajax requests to <code>JSON</code> automatically and it's been working fine.</p>
  
  <p>However, I've noticed that sometimes jQuery adds a mysterious <code>&amp;[object%20Object]</code> at the end of the URL right before the anti-cache parameter (<code>_=1472476048876</code> for example), because I also have <code>cache: false</code> set.</p>
  
  <p>When I change processData to be true, the mysterious part disappears. Anyone have any ideas why? I'm using <code>jQuery 2.1.4</code>.</p>
  
  <p><strong>Edit</strong>: I've noticed that the error only is produced when I make an Ajax call via Datatables <code>.load()</code> API. Has anyone else had this issue?</p>
  
  <p><strong>Edit 2</strong>: In response to @war10ck 's great answer, to clarify, I'm making a GET request but I'm not sending any data with it. I create the URL by hand and thus I think that Datatables is adding some data (even an empty object maybe) to my request which is getting turned into <code>[object%20Object]</code>.</p>
