If you are using ASP.NET, yes it is possible, see this post:

If you are using ASP (VBScript), you must fist save the file on the harddrive and later to open the file using this code:
--------------------------------------------------------
Dim strXlsFileName
strXlsFileName = Server.MapPath("<yourFileAndAppRelative>")
Dim objFileSystem
Set objFileSystem = Server.CreateObject("Scripting.FileSystemObject")
If objFileSystem.FileExists(strXlsFileName) Then
Dim objStream
Set objStream = Server.CreateObject("ADODB.Stream")
objStream.Open
objStream.Type = 1 'Binary Type
objStream.LoadFromFile strXlsFileName
Response.Clear
Response.ContentType = "application/octet-stream"
Response.AddHeader "Content-Disposition", "attachment; filename=" & strXlsFileName & ""
Response.BinaryWrite objStream.Read
objStream.close
Set objStream = Nothing
Response.End
End If
