title: X-Domain Cookies in iFrames
body: <p>I have a domain A.com which is my website. I want to allow the user to login and then I have embedded an iframe into domain B.com which attempts to grab the cookie from A.com to allow the user to be continued to be signed in.</p>
  
  <p>I can't seem to get this working in IE ? A new session gets set instead and the cookie is never retrieved.</p>
  
  <p>I have set a P3P policy ? Any ideas what I am doing wrong.</p>
