Para lograr esto, el backend `:80` debe tener una lista de "orígenes permitidos".

En este caso, la lista tendría que incluir `http://localhost:8080` para que el frontend `:8080` funcione correctamente.

## Comodines { #wildcards }

También es posible declarar la lista como `"*"` (un "comodín") para decir que todos están permitidos.
