# Redirect base URL by language
# We use HTTP status code 302 because it's dynamic and might change in future requests
# We use force (!) because Hugo generates an alias in public/index.html tot redirect to the default language when defaultContentLanguageInSubdir is true
/ /de/ 302! Language=de
/ /fr/ 302! Language=fr
/ /en/ 302!

# Custom 404 error pages
/de/* /de/404.html 404
/fr/* /fr/404.html 404
/* /en/404.html 404
