because my html content i want to show is only for logged-in users.
with this js solution every not logged in user can access the .js file over the url which is included always (in the login page too)
http_s://forum.domain.tld/theme-javascripts/83c1451748e441c882ef44430f033c57bb1ab1dd.js
and can see my js-injected html thats only for logged-in users.
i need a secure solution, not css/js pseudo secure solution.
