forcing file download location dialog rather than viewing linked file?

You need to set the proper headers on the page that renders the file:

Code:

<?php
header('Content-Type: text/plain');
header('Content-Disposition: attachment;filename="youfile.txt"');
header('Cache-Control: max-age=0');
?>

CodeIgniter's Download Helper does this for you also.
