Request.ServerVariables("SERVER_NAME")'

要完成,我的一个功能：

function PageUrl
     dim sPort
     sPort = Request.ServerVariables("SERVER_PORT")
     if sPort = "80" then
        sPort = ""
     else
        sPort = ":" & sPort
     end if

     PageUrl = "http://" & Request.ServerVariables("SERVER_NAME") & sPort & _
                           Request.ServerVariables("URL") & "?" & _
                           Request.ServerVariables("QUERY_STRING")
  end function
