IE6 and PDF download issues...Change page headers

[pthawkes]

Hello

I am having problems downloading a pdf file that I generate on the
fly. The file download will work in IE7 and Firefox, but not in IE6 as
per this post http://drupal.org/node/93787

I am trying to change my headers as the post suggests, with the code
below ...I run this in Firefox with the firebug add-on so that I can
capture the header information sent to the browser and only some of
the setting are changed and it seems to ignore the request that I am
making. Could anyone shed some light on this???

Basically I'm trying to set the Cache-Control to private and the
Pragma to cache

Dim streamObj As FileStream =
File.OpenRead(Server.MapPath(theFile))
'Store File in Buffer
Dim buffer(CInt(streamObj.Length)) As Byte
'Read File from Buffer
streamObj.Read(buffer, 0, buffer.Length)
'Close FileStream Object Set its Value to nothing
streamObj.Close()
streamObj = Nothing

Response.Expires = 0
Response.ContentType = "application/pdf"
Response.AppendHeader("Content-length",
buffer.Length.ToString())
Response.AppendHeader("Content-Disposition:",
"attachment; filename=Your_File.pdf")
Response.AppendHeader("Pragma", "Cache")
Response.AppendHeader("Cache-control", "private")
Response.OutputStream.Write(buffer, 0, buffer.Length)
Response.OutputStream.Flush()

Response.End()
Catch ex As Exception
