I don't see how you can send a document and a redirect in the same stream.
If you send a document with a Location header the browser should ignore the
body
of that document and instead send another request for the specified
location.
If this works on some browsers, or on some sites, then I'd take that as a
fluke not to
be relied upon.
I guess the method could succeed if the body of the original document is
received
quickly enough before the subsequent one starts to download.
Best to steer clear of anything that goes against the way the protocol is
supposed to behave.
I just ran a quick test;
<?php
header("Content-Disposition: attachment; filename=doc.doc");
header("Content-Type: application/octet-stream");
header("Location: ./thanks.php");
echo readfile('./doc.doc');
?>
I never get the document.. just the thanks page. This is what I'd expect.
You say you get the download but not the redirect, which is odd!
I'd put it down to browser nuances and use a more reliable method.
I would suggest sending back the thanks page first which provides a link
and/or Javascript
invocation of the download. This will of course mean maintaining the state
of validation on
the server between requests.
