You should use 127.0.0.1 or localhost instead of a.b.c.d at the first
occurrence.

The [P,L] options mean that the rewrite is a reverse proxy (P) and it is
the last one to be executed if it matches (L). So the rewrite won't be
communicated to the client. From what you wrote, I would think that you do
not have the proxy module loaded. Could you please confirm us that the
mod_proxy is enabled and loaded?

Also, add this snippet (tested with apache2, not sure if it works on apache
1.3) to your virtual host configuration:

    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    <IfModule mod_proxy.c>
        ProxyVia On
        # prevent the webserver from beeing used as proxy
        <LocationMatch "^[^/]">
            Deny from all
        </LocationMatch>
    </IfModule>

Cheers,
