301 redirect when moving a site to a new domain?

Question

URL Handling

Hello, tell me please. The question arose of transferring the site to a new domain, the main mirror of the old https domain and the new domain will also be the main https mirror. The question is how to make the correct redirect?

Answer 1

Option 1
RewriteEngine On
RewriteCond %{HTTPS} =off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [QSA,L]
Option 2
RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$
RewriteRule .* https ://%{SERVER_NAME}%{REQUEST_URI} [R,L]
if both of the first options fail and a circular redirect occurs:
Option 3
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_UR
