方法一
<%
'常用函数
'1、输入url目标网页地址，返回值getHTTPPage是目标网页的html代码
function getHTTPPage(url)
dim Http
set Http=server.createobject("MSXML2.XMLHTTP")
Http.open "GET",url,false
Http.send()
if Http.readystate<>4 then
exit function
end if
getHTTPPage=bytesToBSTR(Http.responseBody,"GB2312")
set http=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
Function BytesToBstr(body,Cset)
dim objstream
set objstream = Server.CreateObject("adodb.stream")
objstream.Type = 1
objstream.Mode =3
objstream.Open
objstream.Write body
objstream.Position = 0
objstream.Type = 2
objstream.Charset = Cset
BytesToBstr = objstream.ReadText
objstream.Close
set objstream = nothing
End Function

txtURL=server.MapPath("../index.asp")

sText = getHTTPPage(txtURL)

Set FileObject=Server.CreateObject("Scripting.FileSystemObject")
filename="../index.htm"
Set openFile=FileObject.OpenTextfile(server.mapPath(filename),2,true) 'true为不存在自行建立
openFile.writeline(sText)
Set OpenFile=nothing

%>
<script>
alert("静态网页生成完毕");
history.back();
</script>

方法二：

resourcefile=server.MapPath("../index.asp")
targetfile=server.MapPath("../index.htm")
Set html = Server.CreateObject("CDO.Message")
html.CreateMHTMLBody resourcefile,31
indexcode=html.HTMLBody
Set html = Nothing
if instr(indexcode,"</BODY></HTML>")<=0 then
response.Write("首页生成失败")
response.End()
else
Set oFileSys = Server.CreateObject("Scripting.FileSystemObject")
Set outfile=oFileSys.CreateTextFile(targetfile)
outfile.WriteLine indexcode
outfile.close
Set outfile=nothing
set oFileSys=nothing
response.Write("首页生成完毕!")
end if
