I've got a script that sends a pdf to the browser for download, and then should re-direct the user to my home page.

The pdf downloads correctly but the re-direct isnt working, what am I doing wrong?

<%@LANGUAGE="VBSCRIPT" CODEPAGE="1252"%>
<%
Option Explicit
Const adTypeBinary = 1
Dim objStream
Set objStream = Server.CreateObject("ADODB.Stream")

objStream.Open
objStream.Type = adTypeBinary
objStream.LoadFromFile Server.MapPath("..\..\") & "\data\downloads\Profile.pdf"

Response.Buffer = True
Response.Clear
Response.AddHeader "Content-Disposition", "attachment; filename=Profile.pdf"
Response.AddHeader "Content-Length", objStream.Size
Response.Charset = "UTF-8"
Response.ContentType = "application/octet-stream"
Response.BinaryWrite objStream.Read
Response.Flush

objStream.Close
rsDocs.Close
Set objStream = Nothing

Response.Redirect("/home.asp")
%>

Once you stream, the redirect will never be called.

One way around this is to spawn an extra window for the stream and then to redirect the original window.

By spawn an extra window do you mean using a pop up window?
Would this be done using JavaScript in the html once the page has loaded?

How would I do that?

Provide a link for the streaming window like this:

<a href="streamingPage.asp" target="_blank">Streaming Page</a>


If you want to move your current page back to the home page with this link, then you could try:

<a href="streamingPage.asp" target="_blank" onClick="location.replace("home.asp")">Streaming Page</a>

Glad to have helped.

Any reason for the grade of B, then?

Sorry, no offence, your answer was quite right!

I'm still quite new to all of this, is there any way I can change it?
