I want to extract just the "domain" and "extension" parts from an nginx
server_name for use as variables later in nginx conf.

For example,

  server_name <some PERL regex ... ?<domain> ... ?<extension>
  location = /test.html {
          alias /local/path/to/$domain.$extension.html;

No matter what the server_name contains, from




and variations in between,the result should be

  $domain = mydomain
  $extension = tld

I found this post

  "Perl Regex to get the root domain of a URL"

that suggest this perl regex


works to extract & return "domain.tld" from any from of input URI.

What's the right form of that regex in nginx's server_name to populate
<domain> and <extension> variables for subsequent use?
