thats a good one 🙂
btw, i tried the script, doesnt work with me either 🙁
anyway it should be
header("Refresh: 0;url=".urlencode($goto));
without the last dot"ation.
actually i dont know too much about headers. what are trying to do. if you want to redirect the user to another page, choose location="http://" instead of url... that would work as i found out.
