Your second iRule should work if you put quotes around the redirect: 


when HTTP_REQUEST {

HTTP::redirect "https://sub.mydomain.net"
  }
 }

You could also use a string map replacement: 


when HTTP_REQUEST {

  set host [string map {mydomain.net sub.mydomain.net} [HTTP::host]]
  HTTP::redirect "https://$host[HTTP::uri]"
  }
 }
