I have been attempting to .htaccess redirect a particular URL in WordPress without any luck. This is what I am attempting to accomplish:

/feed and /feed/ should redirect to FeedBurner

BUT any feed URL which has /feed/?... shouldn't redirect

Everything I have attempted redirects EVERYTHING with /feed (including /feed/?) inside it to FeedBurner.

Any ideas?

RewriteRule ^feed/?$ http://path/to/feedburner

Should work. Are you able to show what you've attempted?
