I'm trying to get Apache to redirect all http and https traffic to a single endpoint www.example.org. The http part is easy:

<VirtualHost *:80>
    ServerName example.org
    Redirect permanent / https://www.example.org/
</VirtualHost>

# long list of other domains, all redirecting to https://www.example.org/

<VirtualHost *:80>
    ServerName www.example.org
    Redirect permanent / https://www.example.org/
</VirtualHost>

I'm trying to do something similar for the https. It is my understanding that I need to specify one specific IP address, because the Host directive is also sent encrypted. So the below works:

<VirtualHost xx.xx.xx.xx:443>
    ServerName www.example.org
    # actual stuff happening here
</VirtualHost>

However, when I start adding the redirects to the config, like so:

<VirtualHost xx.x.xx.xx:443>
    ServerName example.org
    Redirect permanent / https://www.example.org/
</VirtualHost>

# long list of other domains

stuff breaks.

$ apache2ctl configtest 
[warn] VirtualHost xx.xx.xx.xx:443 overlaps with VirtualHost xx.xx.xx.xx:443, the first has precedence, perhaps you need a NameVirtualHost directive

If I add a directive like so:

NameVirtualHost xx.xx.xx.xx:443 

Connecting to the (ssl part of the) server starts to fail.

How do I solve this?
