WordPress Multisite: an official and definitive way to enable https ? (http to https)

I actually just finished setting up https on a multisite here – https://wpexplorer-themes.com/ – personally we are using CloudFlare so we just create a new page rule inside our dashboard to redirect traffic. The way to set things up depends on your server for example on WPEngine when you setup your SSL there is a button in the WPE dashboard to force HTTPS on the site and if you don’t use that and use a .htaccess tweak instead you could end up in an endless loop. I highly recommend asking your host or consulting your hosting company’s documentation to see what the best way is.
