I have a cloud application with subdomain per customer on Domain B.
Customer1 now wants to link to the application to use a subdomain of his own domain A. E.g. app.A.com
The cloud application depends on the subdomain (customer1), because it is using this as marker for loading the correct data. Is it possible in any way to "hide" the application behind another domain/subdomain (e.g. with CNAME)?
