I’ve got two domains linked to my account with one mirroring (mirrorring?) the other. I’d like to do the same for all subdomains, preferably without too much manual configuration. So domain1.com mirrors domain2.com, and I need subdomain.domain1.com to mirror subdomain.domain2.com (along with a list of others). Is there a handy way to do this with DNS records and/or DH’s control panel, or do I need to do it manually or delve into .htaccess rules for this?
