I am trying to write a routine that allows users to download files from our secure site, with the code below the file will download and when you click save i get an IE error. However when the page is not https the routine runs just fine. Any Ideas? or Directions are appreciate?

Sub DownloadFile(file)
'--declare variables
Dim strAbsFile
Dim strFileExtension
Dim objFSO
Dim objFile
Dim objStream
'-- set absolute file location
strAbsFile = Server.MapPath(file)
'-- create FSO object to check if file exists and get properties
Set objFSO = Server.CreateObject("Scripting.FileSystemObject"
'-- check to see if the file exists
If objFSO.FileExists(strAbsFile) Then
Set objFile = objFSO.GetFile(strAbsFile)
'-- first clear the response, and then set the appropriate headers
Response.Clear
'-- the filename you give it will be the one that is shown
' to the users by default when they save
Response.AddHeader "Content-Disposition", "attachment; filename=" & objFile.Name
'Response.AddHeader "Content-Disposition", "inline;" & objFile.Name
Response.AddHeader "Content-Length", objFile.Size
Response.ContentType = "application/octet-stream"
Set objStream = Server.CreateObject("ADODB.Stream"
objStream.Open
'-- set as binary
objStream.Type = 1
Response.CharSet = "UTF-8"
'-- load into the stream the file
objStream.LoadFromFile(strAbsFile)
'-- send the stream in the response
Response.BinaryWrite(objStream.Read)
objStream.Close
call logevent(0,"Done, I think."

Set objStream = Nothing
Set objFile = Nothing
response.End
Else 'objFSO.FileExists(strAbsFile)
Response.Clear
Response.Write("No such file exists."
call logevent(0,"No such file exists."
End If
Set objFSO = Nothing
End Sub


sub main

Dim strPath
strPath = CStr(Request.QueryString("file")
'-- do some basic error checking for the QueryString
If strPath = "" Then
Response.Clear
Response.Write("No file specified."
call logevent(0,"No file specified."
Response.End
ElseIf InStr(strPath, ".." > 0 Then
Response.Clear
Response.Write("Illegal folder location."
call logevent(0,"Illegal folder location."
Response.End
ElseIf Len(strPath) > 1024 Then
Response.Clear
Response.Write("Folder path too long."
call logevent(0,"Folder path too long."
Response.End
Else
Call DownloadFile(strPath)
End If


end sub
