上面的代码在代码第二次生成的时候不会更新，下面的代码加上时间就好了！

[Code]<%
function getHTTPPage(byval url)
  if instr(url,"?")>0 then
    url=url&"&d="&now()
  else
    url=url&"?d="&now()
  end if
    dim   httpxml
   Set httpxml= server.CreateObject("msxml2.XMLHTTP")
    httpxml.open "get",url,False
    httpxml.send()
     if httpxml.readystate<>4 then
  exit function
end if
  getHTTPPage=bytesToBSTR(Httpxml.responseBody,"GB2312")
    set httpxml=nothing
  if err.number<>0 then err.Clear
   end function           ‘ 2、转换乱玛，直接用xmlhttp调用有中文字符的网页得到的将是乱玛，可以通过adodb.stream组件进行转换
