.htaccess code to redirect non www to www http:// and https://

Most of the users are looking for .htaccess code to redirect http:// to https:// and even after they need to know what exactly to add redirect non www to www for both http:// and https://

Here is the exact .htaccess code for same, this code needs to be placed in .htaccess

RewriteEngine On
RewriteCond %{HTTP_HOST} ^[^.]+\.[^.]+$
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

So, suppose if you have a domain say domain.com it will redirect to http://www.domain.com
And if you try to visit https://domain.com it will redirect you https://www.domain.com

Let me know, if still anybody need any assistance.
