title: Ajax issue with Zscaler
body: <p>On my page I have this ajax call:</p>
  
  <pre><code>$.getJSON(
      "@Url.Action("GetSchedulers")",
      { start: start, end: end },
      function(data) {
         fillCalendar(data);
      }
  );
  </code></pre>
  
  <p>Everything works OK, except when I try to access it behind a Zscaler proxy, then the browser returns a CORS error:</p>
  
  <pre><code>"No 'Access-Control-Allow-Origin' header is present on the requested resource."
  </code></pre>
  
  <p>The Request url is <code>https://gateway.zscaler.net/auD?origurl={my_url}</code>.</p>
  
  <p>Does anyone know how to send the request without it being filtered by zscaler?</p>
