How to mitigate

Proxying to external services, like this – using a rule such as /proxy/* https://api.example.com/:splat 200 – is still permitted and this behaviour is not impacted.

I am a bit confused:

1. what is the correct way to show the user a page from another site (no nelify) but still keep him in the current domain?
