How to change the site address to another domain?

Question

open server

Hello, how can I make sure that I go to the site from my iPhone, and my copy replaces it. Only for me!!! You can at least on a local, the main thing is that it should be visible in the address bar of a mobile browser on my smartphone - the address of the original, and the site itself is my copy.

Answer 1

In the hosts file, write
127.0.0.1 site.ru,
or whatever IP address you have for the domain.

Answer 2

There is an option through such a crutch:
Set up work on the Iphone through your proxy, and in the Proxy settings, correct it as you need.
The question is for what purpose do you need it. If for personal use, then the solution is quite convenient.
