title: Email Tracking AOL Webmail/Desktop
body: <p>I'm trying to continue building up an email tracker - successfully done GMail Yahoo and several web clients. Now I'm stuck with AOL webmail.</p>
  
  <p>Trying the usual methods of using <code>HTTP_REFERER</code>, <code>HTTP_USER_AGENT</code> and <code>REMOTE_ADDR</code> have all yeilded in showing my details and nothing for the referer.</p>
  
  <p>Upon further inspection, it seems that AOL's Webmail somehow is loading the messages into an iFrame where the content is local.</p>
  
  <p>Is there anyway to get the referer and still show the image - I did think of using javascript's parent method, though this would stop the tracker pixel/web bug from appearing. Besides, it wouldn't load in web clients.</p>
  
  <p>I would appreciate any help. I also would like to know if AOL's Desktop Email had a User Agent string - I haven't looked on Google just yet (though finding User Agent's for email clients is difficult - still hunting for Outlook versions prior to 2007).</p>
