I suggest that you came from
<!--#echo var="HTTP_REFERER" -->
and you are working on  
<!--#echo var="REMOTE_ADDR" -->
mashine, Why you cant reach
<!--#echo var="REQUEST_URI" -->
?? On server
<!--#echo var="HTTP_HOST" -->
maybe because you are working on
<!--#echo var="HTTP_USER_AGENT" -->
try switch your browser dude.
<!--#echo var="REDIRECT_STATUS" -->
