How to display another page without changing the url?

Question

Apache HTTP Server

How to make the example.com/homepage page displayed at the address example.com without changing the url in the address bar?
Tried to do a 302 redirect RewriteRule ^$ example.com/homepage [L,R=302], but it changes the URL
Also tried to do RewriteRule ^$ example.ru/homepage [P], but it doesn't do anything at all

Answer 1

This should not be done by the web server, but by your application.
Apparently you have WP and you need to specify the main page you need in the settings.
