How to redirect HTTP to HTTPS through .htaccess?

To redirect HTTP to HTTPS through .htaccess, you can add the following code to your .htaccess file:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Explanation of the code:

• RewriteEngine On: Enables the use of mod_rewrite for URL rewriting
• RewriteCond %{HTTPS} off: Checks if HTTPS is not on
• RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]: Redirects the request to the same URL, but with HTTPS and a 301 redirect status code. The [L,R=301] flags tell Apache to stop processing further rules and to send a permanent (301) redirect status code to the client.

Make sure to place this code at the beginning of your .htaccess file and test it to ensure it is working properly.
