How to get the requesting URL

[magic kat]

How can I get the full url of the page that is calling my page? I tried the
below, but it gives me my page, not the page that redirected to me.
' Dim sURL as String

'if strcomp(Request.ServerVariables ("HTTPS"), "ON", 1) = 0 then

' sURL = "https://"

'else

' sURL = "http://"

'end if

' sURL = sURL & Request.ServerVariables ("SERVER_NAME")

' sURL = sURL & Request.ServerVariables ("SCRIPT_NAME")

' if len(trim(Request.QueryString.tostring)) > 0 then

' sURL = sURL & "?" & Request.QueryString.tostring

'end if

'Response.Write(sURL)

Thanks.

Request.ServerVariables("HTTP_REFERER")

However, this can't be relied upon, as some browsers are able to spoof it,
and many ISPs strip it from the Request headers...
