 * I am trying to map an http domain to an https subdomain of my multisite. This
   plugin is installed and activated, and in the dashboard of the subdomain in question
   I am adding the name of the external domain I want to map. The empty field shows
   http, but when I enter the domain and it appears in my list of available domains
   to make primary, it’s shown as https. Obviously the external http domain doesn’t
   have a cert on it, and so this is resulting in a security warning when you try
   to visit it.
 * I understand how to deal with this one particular instance–just slap a cert on
   the external domain. What I want to know is, how do I deal with this on an ongoing
   basis, if I have lots of domains I want to map? Do they all have to be https?
 * I am forcing HTTPS for this network with a page rule in Cloudflare, but I am 
   loathe to disable it. If using https on external domains is a requirement for
   mapping to secure subdomains, I’m fine with that. I just haven’t seen that actually
   set down anywhere as a rule, so I guess I am asking to have that clarified.
 * Thanks for a great plugin.

 * Actually, I was mistaken when I said putting a cert on the external domain would
   fix the https issue. I’ve tried this, and I get an error saying that the external
   domain is trying to use the wildcard certificate for the multisite. Why would
   it be trying to do this?

 * Do you have a mutliple domain SSL certificate?

 * No. It looks like there is another situation causing a cascading series of problems,
   namely the httpd.conf file at my host. It doesn’t seem to involve this plugin
   at all, so I will mark this as resolved and re-post if I am still having problems.
   Thanks for your response.
