Maybe i did not search hard enough, but i miss a page in DokuWiki.org wich tells how to setup DW on a Webserver and using HTTPS connections only. I only found hints about securing the login.
I would add such page and try to link it in all places where it belongs, if it does not exist, or is "hidden" somewhere.
What a was looking for, was a rewrite rule in .htaccess for Apache, but there are many other ways to do. Even more Environments. Well, most of the work is already done on the page
https://www.dokuwiki.org/tips:httpslogin or
https://www.dokuwiki.org/rewrite but not in the context to only secure the service.
I find, these days no one should run a webserver with plain HTTP. So i think it can have an exposed place in installation docs.
