Basically, how do drag and drop website builders, create subdomains for you work (server-wise)?ie instantly serve new website after hitting publish, under a provision subdomain .
so far i understand i can useusing a wildcard subdomain (*.example.com) and possibly a corresponding wildcard SSL as well.using nginx -s reloadA simple DIY website builderusing the setup above but with wildcard subdomain
but I don't understand is how to server a subdomain so quickly. In my experience, every time I made new subdomain, I needed to restart the nginx server.any guide help with understanding this space and resources.
