Functional plugin, friendly dev

Initially had some issues with this plugin working properly, so I contacted the plugin author. He was extremely friendly and very fast to respond, and he added some code to fix my issue.

Plugin works perfectly now with WP 4.8 and Varnish 5, and I’m very happy with it. I’d recommend it over the other Varnish plugins at this point, because it works with Varnish 5 and most others seem to be stuck on 3 or have limited support for 4.
