[wp-hackers] Throw 404 error via plugin

[Ryan Bilesky]

No luck.  I am hooking into init, checking to see if I want to allow the
user to access it.  If not throw a 404 error.

<?php
add_action('init','not_found_test',0);
function not_found_test() {
 global $wp_query;
     if (1=1) {
             status_header('404');
             $wp_query->set_404();
 }
}
?>
