Returning to Default.aspx after downloading file.

After the user downloads a file from filedownload.aspx I am unable to get
them back to the default page for my site. Any suggestions?

code from filedownload.aspx

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load

Dim filename As String = DirectCast(Session("FileName"), String)
Dim filepath As String = DirectCast(Session("FilePath"), String)
Dim fullpath As String = filepath + "\" + filename
Response.Clear()
Response.ContentType = "application/octet-stream"
Response.AddHeader("Content-Disposition", _
"attachment; filename=""" & filename & """")
Response.Flush()
Response.WriteFile(fullpath)

End Sub

This forces the download file dialog in explorer. I get an error when
adding a redirect after Response.WriteFile(fullpath). It says you cannot
redirect after headers have been written. Dunno, please help.
 
Can't do it this way. The reason is, a response.redirect sends a particular
response to the browser (302 I believe) that the page has moved. This must
be done before other content is sent. Redirecting after the stream has been
sent to the browser would screw the browser up royally. I'm not sure if
server.transfer would work in this case, but it's worth a shot.
 
you are allowed only one response. you can return content or a redirect, not
both. in the download link set the target to a new window. then use client
script to navigate.
