title: How can an access token be shared between server names? (www vs non www)
body: <p>I am currently developing an app via website and the token that Facebook returns back will only be in session for the exact url. In other words, if a user hits site.com and logs in, the token only works for site.com. If the user tries to manually type in www.site.com, the token does not apply. </p>
  
  <p>Any ideas?</p>
