在IE进行文档链接时,如果遇到OLE支持的文档,IE会自动调用相应程序打开它,有时候这种功能并不是我们所需的，虽然我们可以提醒用户用鼠标右键-->"目标另存为...."命令来下载文档，但这样毕竟不太友好，本文描述了利用FSO及Stream方法实现IE直接下载文档。
主程序代码如下：
--------------------------------------------------------------------------------
'定义所有需要使用的变量
Dim strFilename,S,Fso,F,intFilelength
strFilename = Server.MapPath(Trim(Request("File")))
Response.Buffer = True
Response.Clear
Set S = Server.CreateObject("ADODB.Stream")
S.Open
S.Type = 1
On Error Resume Next
Set Fso = Server.CreateObject("Scripting.FileSystemObject")
If Not Fso.FileExists(strFilename) Then
Response.Write("<h1>Error:</h1>"&strFilename&"你要下载的文件不存在！<p>")
Response.End
End If
Set F = Fso.GetFile(strFilename)
intFilelength = F.Size '获取文件大小
S.LoadFromFile(strFilename)
If Err Then
Response.Write("<h1>Error： </h1>Unknown Error！<p>")
Response.End
End If
Response.AddHeader "Content-Disposition","attachment;filename="&F.name
Response.AddHeader "Content-Length",intFilelength
Response.CharSet = "GB2312"
Response.ContentType = "application/octet-stream"
Response.BinaryWrite S.Read
Response.Flush
S.Close
Set S = Nothing
