The same kind of thing here--just change the path part to match your environment:


<HTML>
<HEAD>
<META NAME="GENERATOR" Content="Microsoft Visual Studio 6.0">
<TITLE></TITLE>
<%
Function downloadFile( strFile, strDownloadFilename )
     Dim strFilename,objStream,objFilesystem,objFilestream
     Dim intFileLength
     ' get full path of specified file
     strFilename = Server.MapPath( "../Uploads/temp/"  & strFile)
     ' clear the buffer
     Response.Buffer = True
     Response.Clear

     ' create stream
     Set objStream = Server.CreateObject("ADODB.Stream")
     objStream.Open

     ' set as binary
     objStream.Type = 1

     ' check the file exists
     Set objFilesystem = Server.CreateObject("Scripting.FileSystemObject")
     if not objFilesystem.FileExists(strFilename) then
          Response.Write("<h1>Error</h1>: " & strFilename & " does not exist<p>")
          Response.End
     end if


     ' get length of file
     Set objFilestream = objFilesystem.GetFile( strFilename )
     intFilelength = objFilestream.size
 
     objStream.LoadFromFile( strFilename )
     if err then
          Response.Write("<h1>Error: </h1>" & err.Description & "<p>")
          Response.End
     end if
     
     'format strFileName
     if Len( Trim(strDownloadFilename) ) > 0 then
          strDownloadFilename = Trim( strDownloadFilename )
     else
          strDownloadFilename = objFilestream.name
     end if

     ' send the headers to the users browser
     Response.AddHeader "Content-Disposition", "attachment; filename=" & strDownloadFilename
     Response.AddHeader "Content-Length", intFilelength
     Response.Charset = "UTF-8"
     Response.ContentType = "application/octet-stream"

     ' output the file to the browser
     Response.BinaryWrite objStream.Read
     Response.Flush

     ' tidy up
     objFilestream.Close
     Set objFilestream = Nothing

End Function
%>
</HEAD>
<BODY>
<%
Call downloadFile( Replace( Request("FILE") ,"/","\"), Request("FILENAME") )
'Response.Write (Request("FILE")  & "----" & Request("FILENAME") )
%>

</BODY>
</HTML>


BTW--I stole this code from someone else, but can't find the reference.

sFileType= Right(strfileName,4)


Select Case sFileType
Case ".asf"
sContentType = "video/x-ms-asf"
