Routing by hostname with port

[ehpc]

I suppose the behavior for routing by hostnames may be wrong.

Imagine we have a gateway with hostname: "app.localhost" and httproute with hostnames: - "app.localhost".

All 3 variants should work as far as I know, because they work with Traefik for example.

1. curl http://app.localhost:31080 -H "Host: app.localhost" is OK
2. curl http://app.localhost:31080 is NOT FOUND
3. `curl http://app.localhost:31080 -H "Host: app.localhost:31080" is NOT FOUND

Right now I can't open http://app.localhost:31080 in my browser because it adds the Host: app.localhost:31080 header like in example 3.
