You can force the visitors of your website to view the site with https:// (an SSL-connection)
To make that possible you need:
- a signed SSL-certificate (either your own certificate or one you bought at EDIS GmbH)
- you will have to put on the two following rewrite-rules in a .htaccess file in the document-root of your website.
First option:
RewriteEngine on
RewriteCond %{ENV:HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
Second option:
RewriteEngine on
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
