[Flow] Question about Languages and URL/Routing

[David Sporer]

Hey Guys,

until now my project uses always the same urls for both languages and I'm
determining the language by the users' locale.
If the user changes the language I'm saving this in a session parameter so
it doesn't switch back on the next page.

But as I said, the URL is always the same.
How can I configure german as default language and use the same URLs for it
I'm using right now e.g. https://portal.passcreator.de/
and for the english version https://portal.passcreator.de/en/?

Is this just a Routing issue or do I have to do something more?

Regards
David
