title: Ajax Request Rejected
body: <p>I am trying to upload a file using an (jquery) AJAX request but it fails and the response sent is </p>
  
  <p><code>Request Rejected</code></p>
  
  <p><code>The requested URL was rejected. Please consult with your administrator.
  Your support ID is: xxxxxxxxxxxxxxx and provide steps to replicate the issue</code></p>
  
  <p>I've tried to visit the URL using browser and that works fine.</p>
  
  <p>Is there anything related with the AJAX request or is it entirely a server side issue? How can I solve this?</p>
