All of the content of the domains are the same. Because all domains load from a unique host.
So my question is: Should I pay 20$ per domain to have this or can I pay once 20$ per month for all domains. because other domains just alias domain and the content is the same and points to the same host.
I’m pretty sure, because domain2 will be a CNAME for domain1, which has WAF and Page Rules, but I’m going to call in the other @MVP members to verify how this works.
