We're developing an application that has the ability to run across multiple top level domains, each with its own sub domain. (www.foo.com, www.bar.com, would each point to the same application on the same server, mobile sub domains pointing to a different application on the same server.)
Reading up on certificate creation for multiple domains leads me to believe that it is possible to do so, having one certificate that would govern each of the domains that are listed during setup.
However, if we were required to add extra domains to that certificate after its creation, would this be possible? Either through some kind of renewal type process? Or editing and reapplying the certificate?
