title: Cross domain PHP Sessions
body: <p>I am building a site which allows a user to point a CNAME record at my site to run their "profiles", this allows your OWN domain name to load your profile on my site.</p>
  
  <p>This is raising all sorts of issues related to sessions.  I have seen virb do it.  I don't see any of the information that is session based in an iFrame... but there IS an iFrame present on the page.</p>
  
  <p>I can get the domain stuff to work, I just lose session data...  Any ideas?</p>
