ProxyPass SSL over two local Apache instances

I have a Debian server running 2 Apache server instances locally

The reason is one is running PHP 5.2 and the other is PHP 5.3

I have a macro to proxy off to the 5.3 server on certain directories. I specify the directories in a virtual host declaration

This is the macro

<Macro NewPHP>
        ProxyRequests Off
        <Proxy *>
                Order deny,allow
                Allow from all
        </Proxy>
        ProxyPreserveHost On
</Macro>

<Macro NewPHPIn $directory>
        ProxyPass $directory http://127.0.0.2/$directory
</Macro>

And I use it like so

<VirtualHost *>
        ServerAdmin webmaster@localhost
        ServerName foo.co.nz
        DocumentRoot /var/www/foo.co.nz

        <Directory /var/www/foo.co.nz>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride all
                Order allow,deny
                Allow from all
        </Directory>

        Use NewPHP
        Use NewPHPIn /bar/
</VirtualHost>

This makes http://foo.co.nz run on PHP 5.2

And http://foo.co.nz/bar run on PHP 5.3

Now the problem is I need to do that same for SSL but I cant figure out how to get it working. Ive tried lots of different things and cant find any help elsewhere.

Does any one have any idea that may help?
