ASP有函数可以把某个网页通过STREAM下载

<script language="vbscript">

Function bytes2BSTR(vIn)

Dim strReturn,i,ThisCharCode,innerCode,Hight8,Low8,NextCharCode

strReturn = ""

For i = 1 To LenB(vIn)

If ThisCharCode < &H80 Then

strReturn = strReturn & Chr(ThisCharCode)

Else

NextCharCode = AscB(MidB(vIn,i+1,1))

strReturn = strReturn & Chr(CLng(ThisCharCode) * &H100 + CInt(NextCharCode))

i = i + 1

End If

Next

bytes2BSTR = strReturn

End Function
