Depending on what you're trying to return, there are a couple
options. In your particular case, I'd swap the order, returning
the page-content with a redirect points to the file-download URL.
This could be an HTML <meta> redirect, JavaScript, or an
<iframe> that points to the CSV file (http://site/csv/url/ for
this example) for download:

HTML: <meta http-equiv="refresh"
content="3;url=http://site/csv/url/" >
Javascript: location.href = 'http://site/csv/url/';
iframe: <iframe src="http://site/csv/url/">

You might also be able to (ab)use an HTML redirect to return the
page while simultaneously redirecting with a 302/307 that would
bounce the user to the given page.

If the use-case was different and you actually wanted to return
multiple files, I've used Python's zipfile module to zip up the
contents and then return the collection (in my case, returning
multiple .csv files).
