plan is to add {locale}
in path parameter of the url, locale values are expected to be "en-US, fr-CH". As per my understanding path parameters should be lower case and dash separated so i prefer to have it as "en-us" but as per locale standards it should be "en-US" with country in caps. what could be the better option among two lister below in this case & share if you have any better option.
Option 1: http://mydomain.***/en-US
Option 2: http://mydomain.***/en-us
