If you want to bust the cache on a version update, a better practice is to stick the version id as a query parameter at the end of resources, see:
https://css-tricks.com/strategies-for-cache-busting-css/

ie http://localhost:8080/auth/resources/themes/login/keycloak/css/login.css?v=1.6.1.final

I thought the point of customized themes were to allow developers better control over the web resources being served without modifying the security source code. But if we can't control the url of our content, it limits our options on web optimization strategies.

I guess overriding the freemaker template is the only way to go.

Subject: Re: [keycloak-user] Theme Resources Urls

Browser caching is turned on for themed resources (admin console,
login, etc.)  This is obviously for performance reasons.

IN the past we received a HUGE amount of false bug reports of "Admin
console doesn't work", "my theme changes aren't showing", etc. after
upgrading Keycloak.  All because people didn't clear their browser
caches.  Hence, the version id.

You should not be externally linking to themed endpoints.  You can use a
different URL to ping the server for "is alive" i.e.
/<root>/realms/{realm-name}
