Configure two virtual hosts for Apache. The first one is the default virtual host the respinds with "403 Forbidden" or something, the second one is the vhost for b.zzz.com. If someone types in a.zzz.com in his browser, he will get the 403 error. Also have a look here: http://httpd.apache.org/docs/2.0/vhosts/name-based.html
