Hi Henrik, Great. Thanks, that helps a lot. It looks like the best way to send all URLs that aren't for www.wikihow.com to the url_rewrite_program is to do this: acl mydomain dstdomain www.wikihow.com url_rewrite_access deny mydomain This seems to do the trick. It wasn't clear to me from the documentation that it was possible to put "allow" or "deny" after url_rewrite_access. Thanks a lot for the help! Travis
