How to return a file in HTTP with a given name

ex.php

<?php
// We'll be outputting a PDF
header('Content-type: application/pdf');
// and It will be called downloaded.pdf
header('Content-Disposition: attachment; filename="downloaded.pdf"');

// The PDF source is in original.pdf
readfile('original.pdf');
?>

ex.py

def handler(req):
    req.content_type = "application/pdf"
    req.headers_out.add('Content-Disposition', "attachment; filename=\"downloaded.pdf\"")
    data = file('original').read()
    req.write(data)
    return apache.OK

Suppose you want to return a PDF via http.
The pdf is named original.pdf, but you want to return it as "downloaded.pdf"

We can use the http headers Content-Type and Content-Disposition. See the PHP and mod_python examples below.

This is useful for documents (pdf, word, images, etc...) generated on the fly on the server.
