title: Can't log in to website within iframe with IE and Chrome. But I can with Safari and FF
body: <p>On both IE and Chrome, if I allow 3rd party cookies from the browser's settings I can login.</p>
  
  <p>However, this isn't a practical solution.</p>
  
  <p>Regarding IE:  Do I need to create a P3P policy and reference it in my iframe website?</p>
  
  <p>Regarding Chrome:  Chrome has always worked fine. Did they change their cookie policy recently?</p>
  
  <p>I have always been able to login to my iframed website. Did anyone else experienced this behaviour?</p>
  
  <p>Any help appreciated, cheers.</p>
