[Mailman-Users] Different URL PATTERNS per virtual host?

I am using Mailman v2.1.6 and I was wondering whether it is possible to have a different DEFAULT_URL_PATTERN per virtual host?

For my main site, example.com, I would like it to use https://%s/mailman for the web interface, but for other sites I host, say example.net, to use http://%s/mailman.

Take care,

Ben
