How to force redirect a subdomain to 'https://www.'?

To force redirect a subdomain to 'https://www.', you can use a combination of server-side configuration and DNS settings. Here's how you can do it:

1. Set up a redirect rule on your web server (e.g., Apache or Nginx) to redirect all requests for the subdomain to 'https://www.'. For Apache, you can add the following rewrite rule to your .htaccess file or virtual host configuration: RewriteEngine On RewriteCond %{HTTP_HOST} ^subdomain.example.com$ RewriteRule ^(.*)$ https://www.example.com/$1 [L,R=301] For Nginx, you can add a similar rewrite rule in the server block configuration: server { server_name subdomain.example.com; return 301 https://www.example.com$request_uri; }
2. Update your DNS settings to point the subdomain to the same IP address as the main domain. This will ensure that all requests for the subdomain will be handled by your web server.
3. Once you have set up the redirect rule and updated your DNS settings, all requests for the subdomain should be automatically redirected to 'https://www.'.

Make sure to replace 'subdomain.example.com' and 'www.example.com' with your actual subdomain and main domain. Additionally, test the redirect to ensure that it is working correctly.
