[Plugin: FeedBurner FeedSmith] Not working with Rss2

Just opened up the plugin to see if I could find the code that might be causing my problem. There seems to be a function ol_check_url() that uses a case statement that switches on the feed document…

function ol_check_url() {
	global $feedburner_settings;
	switch (basename($_SERVER['PHP_SELF'])) {
		case 'wp-rss.php':
		case 'wp-rss2.php':
		case 'wp-atom.php':
		case 'wp-rdf.php':
			if (trim($feedburner_settings['feedburner_url']) != '') {
				if (function_exists('status_header')) status_header( 302 );
				header("Location:" . trim($feedburner_settings['feedburner_url']));
				header("HTTP/1.1 302 Temporary Redirect");
				exit();
			}
			break;
		case 'wp-commentsrss2.php':
			if (trim($feedburner_settings['feedburner_comments_url']) != '') {
				if (function_exists('status_header')) status_header( 302 );
				header("Location:" . trim($feedburner_settings['feedburner_comments_url']));
				header("HTTP/1.1 302 Temporary Redirect");
				exit();
			}
			break;
	}
}

This function is applied at the init hook:

add_action('init','ol_check_url');

I do have permalinks set up on my blog:

http://example.com/2008/04/19/sample-post/

Upon reading the function above, I decided to try this link:

http://mfields.org/wp-rss2.php

…which will redirect to feedburner

while:

http://mfields.org/feed/

Still takes me to my WordPress rss feed.

This is peculiar, has anyone experienced any feed related permalink weirdness with 2.5? I don’t really play with my feeds alot, but I’ve heard the name “Feedburner” about a gizillion times and decided to look into it…. and I kinda like it.

I know that I could just hardcode the links to feedburner, but I would rather try to gain an understanding of why

<?php bloginfo('rss2_url') ?>

fails, while

<?php bloginfo('atom_url') ?>

redirects.
