I have seen requests for this before and it blows me away that nobody has ever spent the time to do it. It took me about 30 minutes. On this test install the document root is /var/www and Boonex is installed at /var/www/boonex. If you installed Boonex to the root of your webserver then simply remove the /boonex folder from BOTH the left and right side of the rule.
