title: IE11 losing session or cookie info after window.open
body: <p>Here's my problem</p>
  
  <ol>
  <li>I have a website(X1.com) which contains a login and a button(window.open) after login to open another app (X2.com) in a detached window. </li>
  <li>this X2.com has list of items and when I double click an item it is supposed to open X1.com/item1. </li>
  </ol>
  
  <p>All of this was working as expected when I was using IE9, chrome and firefox. </p>
  
  <p>But when updated my IE9 to IE11 double clicking the item on X2.com is taking to the login page of X1.com saying session timed out. Chrome still works fine. When I close/logout and login again to X1.com keeping X2.com window    open X2.com is able to open that X1.com/item1 page properly. </p>
  
  <p>Is there an internet option or security setting or a plugin in IE that's blocking X2.com from opening X1.com/item1 page first time? </p>
  
  <p>My company uses IE11 only for operations and that's why I have to get it working. Please ask if my question is not clear. I can provide the exact urls if required.</p>
