OK, so after a lot of try- and error, seems that even though the config
file mentions 3.0, it is actually still a 2.x config file.

Among other things, purge does not seem to do what it did in 2.x.

I'm not sure I want to ban something from the cache - the purpose (as
far as I understood it) is to remove something from it, so a fresh copy
will be fetched the next access.

Can someone explain how ban takes over the functionality of purge?
