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

I thought I'd share this because it's taken me a couple of hours to work out and the documentation is not entirely clear.

ban wtf?*

First of all, the purge method used to be called purge in Varnish 2.x but they renamed it to ban in 3.0. Confusingly there is also a new command called purge too! The new purge command is much less sophisticated than ban, as (AFAIK) it only purges exactly matched items, so basically one at a time.
If you do wish to use the new purge you need to have some specific VCL in place. See here

  .url = "/index.html";

  .interval = 2s;
  .window = 5;
  .threshold = 3;
