title: ChromeBox app does not use proxy settings in Kiosk mode
body: <p>Using a chrome application on a Chromebox that displays a web page in Kiosk mode, the URL is not found in enterprise because the proxy settings are not taken into account. It works fine in regular browser without kiosk mode.</p>
  
  <p>I may have missed a configuration step ?
  Or is it possible in the application code to specify / force the usage of a proxy ?</p>
  
  <p>(Can be tested with 'Kiosk' application : <a href="https://chrome.google.com/webstore/detail/kiosk/afhcomalholahplbjhnmahkoekoijban" rel="nofollow noreferrer">https://chrome.google.com/webstore/detail/kiosk/afhcomalholahplbjhnmahkoekoijban</a>)</p>
