By default, Demo Registrar Linux Servers have the mod_rewrite module enabled. You can make use of this module to automatically redirect your visitors from HTTP to HTTPS.
Setting the HTTPS Redirection
Step 1: Verify Digital Certificate Installation.
Ensure that the Digital Certificate is properly installed on your Hosting Order, and the site is resolving on https://yourdomainname.com.
Your site will work on https://yourdomainname.com or https://www.yourdomainname.com or https://subdomain.yourdomainname.com, depending on the Common Name for which you had the certificate issued. Resolving HTTPS on anything other than this Common Name would result in a certificate name mismatch error.
Step 2: Add Redirection.
Create a .htaccess file under the site's directory and add the following lines to it. In case there already exists a .htaccess in your site's directory, carefully edit it to add these lines:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://<common_name>%{REQUEST_URI}
Tip
<common_name> needs to be replaced by the Common Name for which the Digital Certificate is issued.
