"Please have a look at my demo site https://www.demo.mydomain.tld". My SSL certificate is only valid for www.mydomain.tld, so your browser will complain and you will have to add an exception to access the site.",
there is no problem for you to connect on my demo site.
But if I say the same to my mother in law, the result can't be predicted.
So I'm looking for a cool way to set ssl exceptions in popular browsers.
Any suggestion ? (other than "get a wildcard certificate" and "use another url")
