Just make language explicit in the URI, eg `example.net/en/` or
`example.net/de/` – and not optional, but required.

All state explicit in the URI. No state on the server.

The only page that wouldn’t use such a namespace and would still
need to be aware of state would be the `example.net/` homepage.
But even that responds with nothing but a redirect, which is easy
to test. (POST a lang pref, then check if the homepage redirects
to the just-selected lang namespace.)

That can be handled the same way: put the username in the URI as
a namespace, then require accesses to such a namespace to have
proper credentials.

All state explicit in the URI. No state on the server.

Again you only need to redirect from one place (the login page in
this case, which is even easier to test than the homepage).
