Seeing as the site route setup has an option to automatically redirect to HTTPS without having to mess around with .htaccess I wondered if you could do a general domain redirect option that would redirect all the attached domains to the first domain in the list? This would mean we could setup a static site and easily redirect the typical no-www to the www. subdomains without having to create a separate PHP app just to use a .htaccess file.
Just to be extra clear. Under Domain info of the route would be:
And a switch box: Redirect to first domain would be toggled on. Then visiting any of the domains other than the first in the list would redirect to the first. E.g. myprimarydomain.com.co.uk -> www.myprimarydomain.com
