We recently ran into this problem ourselves. See this MSKB article

These are the headers we ended up having to use to get it to work over SSL.

header("Expires: Sat, 01 Jan 2000 00:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$file_name\";");
header("Content-length: " . strlen($csv_string));
