.htaccess for Pretty URLs mod and http -> https

[Gerd 66]

The provider supports https. Unfortunately, it does not work 100% on all forums right away.

The .htaccess files of my forums contain entries from the "Pretty URLs mod"

I would also like to make entries for the rewrite from http to https.
example:

RewriteCond %{SERVER_PORT} !=443
RewriteRule ^(.*)$ https://www.domain.de/$1 [R=301]

Can I do this?
If so, should the entries be made at the beginning or at the end of the .htaccess file?

Just put it before any of RewriteRules
