NGINX catch-all for redirecting www and http to non-www https

gistfile1.txt

# Redirect http:// to https://
server {
	listen 80 default_server;
	listen [::]:80 default_server;
	
	server_name _;
	return 301 https://$host$request_uri;
}

# Redirect https://www to https://
server {
	# Setting default_server on these can cause redirect loops.
	listen 443 ssl;
	listen [::]:443 ssl;
	
	ssl_certificate /etc/nginx/ssl/mysite.pem;
	ssl_certificate_key /etc/nginx/ssl/mysite.key;
	
	server_name ~^www.(?<domain>.+)$;
	return 301 https://$domain$request_uri;
}

# Your website details
server {
	# Only listen to 443.
	# default_server works here.
        listen 443 ssl;
        listen [::]:443 ssl;
}

Worth noting that if you use this with Cloudflare you must make Crypto -> SSL set to "Full", or Cloudflare will channel HTTPS requests to port 80 and confuse nginx into an infinite loop.
