I would like to use Flexible SSL for an application I’m planning to host on Azure. I do not control the 2nd level domain (i.e. foo.it) directly, the application would live on a 3rd level domain entry (i.e. app.foo.it) but other services I do not control live under the 2nd level (i.e. institutional web site) and should not be impacted by this. This means I would have to ask the controller of the domain to adjust the configuration of DNS entries. In general I believe this should be technically feasible, but not being an expert I’d like to have a confirmation before embarking this journey.
Would anybody please confirm I’m not missing anything? What steps would I have to go through to coordinate between the owner of the domain name on one side, and the configuration in Azure on the other end?
