Question

I have a situation where domains’ A records will be pointing to my server without my knowledge (ie, I won’t be configuring each one manually), but I want all root requests (e.g. example.com) to be converted or redirected to their www counterpart (e.g. www.example.com). Without having to use the text example.com in my configuration (because I won’t be editing the configuration for each new domain), is this possible to achieve?

I think you can do something like this

server {
  server_name    ~^(www\.)?(?<domain>.+)$;
  root           /sites/$domain/www;
}
