plugin external file needs just db functions NO HEADER

Hi,

I am making a plugin, the main part is working OK until now. I need to add an external file, a download manager, that doesn’t require any themes or anything from WP except the database functions. But I can´t use headers.php because it sends the header information and I don’t want to do that.

I just need to access the database and download a file, that´s all.

I was thinking to use this

<?php
/* Short and sweet */
define(‘WP_USE_THEMES’, false);
require(‘./wp-blog-header.php’);
?>

But I saw it sends the header information, not working for me.

I am thinking to use something like this:

<?php
require(‘./wp-db.php’);
?>

could this work? I haven’t found any reference to this, or maybe I don´t know how to search this…

Thanks in advance, and sorry for my “english”. 😉
