I don't think you can reverse-proxy ssl. Since everything is
encrypted, there is nothing for a reverse-proxy to handle -- just a
raw stream of bytes. For a forward proxy, this is handled using the
CONNECT method; but obviously the client needs to know about the proxy
to use that.

Luckily there is an easy alternative. Just use "port forwarding" at
the OS or firewall-level. Since there is no processing that can be
done at the apache-level (due to the encryption) you don't lose
anything by doing simple port-forwarding.
