Your RegEx ^/(.*) is open for every request. To catch the "root"
request only, change it to ^/$ instead. Your condition checks the host
header. You're redirecting to the same host (www.saddlebrook.com), why
should the host header be different? It should match against your
RegEx if the host www.saddlebrook.com was requested, of course.
