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.

Want to deploy an existing node.js Github project on OpenShift?

Give this recipe a try:

Add our OpenShift starter-code to your existing GitHub-hosted node.js application code:

cd $YOUR_PROJECT_FOLDER # This script assumes that your project is a git repo, with a git remote hosted on github.com
git remote add upstream -m master [email protected]:ryanj/nodejs-custom-version-openshift.git
git pull -s recursive upstream master # merge in a basic OpenShift skeleton

	1) Install cloudflared using homebrew:

	brew install cloudflare/cloudflare/cloudflared

	2) Create /usr/local/etc/cloudflared/config.yaml, with the following content

	proxy-dns: true
	proxy-dns-upstream:
	- https://1.1.1.1/dns-query
	- https://1.0.0.1/dns-query

	// Follow the instructions here: http://mashe.hawksey.info/2014/07/google-sheets-as-a-database-insert-with-apps-script-using-postget-methods-with-ajax-example/
	//
	// That'll get you 80% of the way there. Unfortunately, you'll run into CORS and MIMETYPE errors, so make the following changes.


	// ============================================================
	// Your clientside script should actually look like this (jquery example):
	// ============================================================

	var data = {email: "[email protected]"}

	// Create or open an existing Sheet and click Tools > Script editor and enter the code below
	// 1. Enter sheet name where data is to be written below
	var SHEET_NAME = "Sheet1";
	// 2. Run > setup
	// 3. Publish > Deploy as web app
	// - enter Project Version name and click 'Save New Version'
	// - set security level and enable service (most likely execute as 'me' and access 'anyone, even anonymously)
	// 4. Copy the 'Current web app URL' and post this in your form/script action
	// 5. Insert column names on your destination sheet matching the parameter names of the data you are passing in (exactly matching case)

	# Note (November 2016):

	# Serving static html to Googlebot is now considered bad practice as you should be using the escaped fragment crawling protocol

	server {
	listen 80;
	listen [::]:80;
	server_name yourserver.com;

	root /path/to/your/htdocs;
