{
  "default_language": ...,
  "supported_languages": [],
  "clear_route_cache": ...
}

default_language

(string, REQUIRED) The default language to be used as a fallback. The value will be included in the list of the supported languages.

See https://unicode-org.github.io/icu/userguide/locale/

supported_languages

(repeated string, REQUIRED) The set of supported languages. There is no order priority. The order will be determined by the Accept-Language header priority list of the client.

See https://unicode-org.github.io/icu/userguide/locale/

clear_route_cache

(bool) If the x-language header is altered, clear the route cache for the current request. This should be set if the route configuration may depend on the x-language header. Otherwise it should be unset to avoid the performance cost of route recalculation.
