title: Actix serving on two ports?
body: <p>I want Actix to bind and serve HTTP at two TCP ports at once.</p>
  <p>How to do this?</p>
  <p>Will two <code>App::new()</code> in Tokio <code>select!</code> macro work as expected?</p>
  <p>I'd prefer to have just one <code>App</code>. Then, can I somehow specify port like I specify path through decorating a method?</p>
