I have 180 or so websites that all run of a single MVC app.
The app runs on a domain, which is not accessible directly by the public, and each of the 180 public facing sites are set up as domain aliases of this.
I have always put off using
https because the cost of 180 certs was prohibitive. But recently I started using Let's Encrypt for some other sites and now I want to try it on these.
The problem is, there is a maximum domain alias limit of 100. As Stephen pointed out, I'd like to cover the www and non-www versions, so that's really 360!
Until now I have only used the plesk plugin which makes it REALLY easy. So now when I want to go beyond the 'default' usage, I have absolutely NO idea where to start. I am worried that in my ignorance I will spend days persuing a solution that it was never suitable in the first place!
So I have 3 questions:
What is the easiest / simplest approach for me to get certification for 180 domain aliases with LE? Is it even possible?
It appears that I will need to install an ACME client on the server, is that correct?
We're using Win Server 2012.
Stephen also suggested splitting up the sites into groups of 50. This is do-able but it would require maintaining a number of code bases, which I would prefer not to do, if possible.
