Problem with webclient.downloaddata

[gom]

I am using the following code to stream a server generated pdf file to a
client. Acrobat 7 opens the file as expected but Acrobat 5,6 and 8 launch
in memory but never open. I ran the command with Fiddler running and it
tells me there is a content-length mismatch of 129 bytes between my buffer
length and what the server actually sends. I'm wondering if this is an
issue related to some additional header information or something that is
sent along with the buffer. Can anyone help me with this?

Thanks in advance.

Dim client As New System.Net.WebClient()
Dim buffer As Byte() = client.DownloadData("http://www.mywebsite.com" &
myResponseString.ToString)

If buffer IsNot Nothing Then
Response.ContentType = "application/pdf"
Response.AddHeader("content-length", buffer.Length.ToString())
Response.BinaryWrite(buffer)
End If

try:

Response.ClearHeaders()
Response.ClearContent()
Response.ContentType = "application/pdf"
Response.AddHeader("content-length", buffer.Length.ToString())
Response.AddHeader("content-disposition","inline;filename=report.pdf")
Response.BinaryWrite(buffer)
Response.End()

Tried it and it made the length mismatch smaller but still the same basic
problem.

You need to examine the Response Stream (converted to text) to determine
exactly what is being added to the front of the response. Does the ASPX page
that generates this have anything besides the @Page Directive? If it does,
remove the offending markup.
