title: Iframe site windows authentication giving the pop up even though parent site authenticated?
body: <p>I have designed a website to use windows authentication. Everything works as expected. But my recent task was to integrate another site into this site(I can't re-write the whole application into this). So i have followed to use an iframe. Now my child site also uses windows authentication. So When i hit the parent site it is asking for windows credentials and user validated. When i hit the child site on iframe, it is again giving me the pop up to enter the credentials, Is there a work around for this? Please help.</p>
  
  <p>Note: Both these applications are hosted on the same server.</p>
  
  <p>Thanks in advance.</p>
