Internet Explorer cannot download <filename> from www.domain.tld

P: n/a
http://www.frostjedi.com/terra/scrip.../download2.php

Whenever I get that page, I get the following error:

---------------------

Internet Explorer cannot download download2.php from www.frostjedi.com.

Internet Explorer was not able to open this Internet site. The
requested site is either unavailable or cannot be found. Please try
again later.

---------------------

Here's the source code to download2.php:

<?php
session_start();
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment; filename="emails.csv"');
?>
a
b
....

If session_start() is commented out, it works just fine. I've
narrowed the problem to a particular header that's being transmitted.
Namely, this one:

header('Cache-Control: no-store, no-cache, must-revalidate, post-
check=0, pre-check=0');

If you replace session_start() with that, you'll get the same error.
The only thing is... I'm not sure why that header is being added. I
can fix it by adding header('Cache-control: private');, but I'd still
like to know why it's being added in the first place.

Any ideas?

Known problem: MSIE not storing it in cache, and hence nnot downloadable.
The cache headers are probably from your session_start() (look at your ini
session settings, cache control is one of them).
