Purge (ban) an entire domain in Varnish Cache 3

How to purge ('ban') an entire domain in Varnish Cache 3

#####EDIT: NB Ban is technically different from Purge. Banned objects remain in memory but banning is faster than purging. Read the Varnish 3 documentation here and here.

Purge may be a more appropriate action for your use-case; although the examples in the gist below work, it's not necessarily the best way of doing this.
