persistenceMode="None" means that the localization is not
activated. You need to choose one of the following options for your implementation:
PathPrefix - he language code is inserted as folder in the URL right after application root.
BrowserSettings - Language code is not explicitly persisted and always the first match from browser preferred languages is used.
DomainName - The language is set per domain. This option could be used when you have different language versions and different domain for every language version.
DomainExtension - The language code comes from the top level domain, if it is a country domain (.uk, .it, .es, ...). Else the default language is used.
All the best,
