    Yep. It's the layer called the application server. The main reason for this layer, as opposed to CGI which has no app server, is that the application is persistent as opposed to execute on demand. With a dynamic language like Perl, the benefits of persistence are enormous. Reduced a little–

    AppCode <-> AppServer <-> WebServer

      when setting up nginx as a reverse proxy with Starman at the backend is the upstream directive required ?
      this example perlmaven.com/getting-started-with-perl-dancer-on-digital-ocean does not use upstream
