/**
 * {@link LocaleResolver} implementation based on Spring's built-in
 * {@link CookieLocaleResolver} that falls back to Spring's 
 * {@link SessionLocaleResolver} when no cookie is found.
 * This allows users with cookies disabled to still have a custom
 * Locale for the duration of their session.
