To force HTTPS and www on Symfony 4, you can follow the steps below:

1. Ensure that your server is already configured to use HTTPS and has a valid SSL certificate installed.
2. Open the .htaccess file located in the public folder of your Symfony 4 project.
3. Add the following lines of code at the beginning of the file to force HTTPS redirection:

1
2
3

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

1. To force www redirection as well, add the following lines of code after the HTTPS redirection code:

1
2

RewriteCond %{HTTP_HOST} !^www. [NC]
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

1. Save the .htaccess file.

By following these steps, all requests to your Symfony 4 application without HTTPS or without www will be redirected to the secure version with www.
