Assuming you are running Apache as your web server, have already secured an SSL certificate, and have both ports 80 and 443 open, you can forward all of your HTTP (http://example.com) traffic to HTTPS (https://example.com) and pass the path along as-is using the following configuration file.
<VirtualHost *:80> ServerAdmin admin@example.com ServerName example.com RewriteEngine on RedirectMatch "^/(.+)" "https://example.com/$1" </VirtualHost> <IfModule mod_ssl.c> <VirtualHost *:443> ServerAdmin admin@example.com ServerName example.com RewriteEngine on RedirectMatch "^/(.+)" "https://example.com/$1" Include /etc/letsencrypt/options-ssl-apache.conf SSLCertificateFile /etc/letsencrypt/live/example.com/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/example/privkey.pem </VirtualHost> </IfModule>
When running apache2 on an Ubuntu server this file is can be created at /etc/apache2/sites-available/example.com.conf . Once your file is in place you’ll want to run sudo a2ensite example.com to enable the site and then sudo service apache2 restart to restart your web server and make sure your settings take effect.
