title: Facebook Connect with multiple CNAMEs
body: <p>We have a single application that will be accessed by multiple CNAME routes.  Because Facebook Connect authorizes only 1 single URL for use, any CNAME route causes our Facebook Login to fail.  Multiple Domain capability on Facebook Apps does not solve the issue because each multiple domain: "must be derived from your Site URL or your Mobile Web URL." (that is the exact error message given when multiple domains are attempted).</p>
  
  <p>I can't imagine that someone as large as Facebook would have failed to account for CNAMEs ... but I cannot find any support for them in the documentation and any questions I see regarding this situation around the internet are left unanswered.  </p>
  
  <p>So the question is ... how to provide for Facebook Connect login with a single app accessed via many different CNAME routes?</p>
