How to redirect to https in apache?

Question

PHP

Guys help me make a normal request so that if a person enters

www.site.ru, site.ru, http://www.site.ru, http://site.ru

always, ALWAYS, all the pages that he entered in this way were redirected to https://site.ru . In the net, some kind of nonsense, then a cyclic redirection, then it only works with one thing.

Answer 1

<IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteCond %{HTTPS} !on
   RewriteRule .* https://%{HTTP_HOST}/%{REQUEST_URI} [R=301,L,QSA]
</IfModule>
