How to redirect HTTP call on a port to another port on local env?

Question

Problematic

I would like to call http://myapp.dev in my web browser and "redirect" this call to http://myapp.dev:6547 or http://127.0.0.1:6547, like a proxy would do.

This way, I could have an Apache or nginx listening to 6547 without having to write the port in my web browser to reach MyApp locally hosted.

Question

Is that possible with native Ubuntu/Linux tools to do this?

Solutions proposed

I've seen this post:

• https://stackoverflow.com/questions/10729034/can-i-map-a-hostname-and-a-port-with-etc-hosts

but I don't want to install nginx to do this.

I've also seen this post:

• redirect port 80 to 8080 and make it work on local machine

but iptables are cleaned each reboot and I want a persistent solution without having to install iptables-persistent package.
