NC 11 manual upgrade and SSL CONFIG

Actually I am using 10.01 on a shared installation.

As the actual version shows errors (hashes do not match) I like to manually upgrade to 11.

The actual version uses htaccess an rewrite rules to use SSL of my provider (hosteurope). This worked fine in the past, but seems for me the problem for the updater app.

Actual rewrite rule:
RewriteCond %{HTTP:Via} !
RewriteRule ^{HTTP_HOST}%{REQUEST_URI} [R=301,L]

As I understand version 11 uses a new approach to use SSL and HTTPS.

How would be the config.php and htaccess configuration to use the mechanism for my provider?

Is there any documentation for this here within NC documents?

Best Regards,
