Plugin to prevent WordPress from setting page headers?

Hello,

I’m using WordPress inside of a CodeIgniter framework, and therefore I don’t want WordPress to be setting page headers – I’d rather CodeIgniter handle this.

In the status_header function in wp-includes/functions.php I’ve included this silly little shim:

function status_header( $header ) {
if (file_exists($_SERVER[‘DOCUMENT_ROOT’] . “/system”)) {
// CodeIgniter site, WordPress should not set headers
return;
}
…

This aborts the function when the CodeIgniter “system” directory is found. I might toy around with this and come up with a better way to detect a CI site – perhaps a global variable/constant or something, but if I wanted to create a little plugin to do this so that I don’t have to alter the WordPress code after each release, would this be easy to do? Does the plug-in architecture support such a hack? WIth a plug-in the detection mechanism would simply be “if the plugin is enabled, abort this function”.

Can anybody suggest the best way to go about doing this if not a plug-in, or suggest a more elegant way to go about doing this if such a way exists?

Thanks in advance!
