Can this be done?
And if so how to do?
I tried
<? php
$ url_referer = 'www.facebook.com';
$ ch = curl_init ();
curl_setopt ($ ch, CURLOPT_URL, $ _ GET ['url']);
curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ ch, CURLOPT_REFERER $ url_referer);
$ html = curl_exec ($ ch);
print $ html;
?>
but does not appear as a referral facebook ..
