Response.Clear
if lcase(right(FileName,3))="gif" or lcase(right(FileName,3))="jpg" or lcase(right(FileName,3))="png" then
Response.ContentType = "image/*" '对图像文件不出现下载对话框
else
Response.ContentType = "application/ms-download"
end if
Response.AddHeader "content-disposition", "attachment; filename=" & GetFileName(Request.QueryString("FileName"))
Set Stream = server.CreateObject("ADODB.Stream")
Stream.Type = adTypeBinary
Stream.Open
Stream.LoadFromFile Server.MapPath(Request.QueryString("FileName"))
While Not Stream.EOS
Response.BinaryWrite Stream.Read() '分64块下载
Wend
Stream.Close
Set Stream = Nothing
Response.Flush
Response.End
%>
保存为:fileDownload.asp
使用：fileDownload.asp?FileName=files/test.rar
