We've got a SharePoint 2013 farm, where we won't be able to get a wildcard certificate for the app domain (corporate regulations).
As we only want to develop provider-hosted apps (mainly ASP.NET MVC and MVC Web API), the question came up, if it is possible to set up SharePoint in a way that we can develop (high-trust) provider-hosted apps, without configuring the app domain part of the farm and still use https for SharePoint and the apps.
I think it should be possible, because I already successfully tested our provider-hosted apps after clearing the app domain setting in the CA and removing the DNS entry (e.g. *.appdomain.com) for it, but I need to be sure ;-)
Has anyone tested this and can confirm that it is possible?
