public class HttpAcceptLanguage extends LocaleSource
HttpAcceptLanguage class is a locale source class that carries the language preference of the web client.
On each request, the language preferences of the web client are conveyed by the Accept-Language item in the HTTP header. The language preference can be composed of multiple locales. For example, when the client sets the language preferences to French, English, German, and Japanese in this order, the Accept-Language value would be as follows:
Accept-Language: en;q=0.9, fr;q=1.0, de, jaConsidering the locales supported by the application, the
HttpAcceptLanguage object is instantiated with this value to determine the current user locale. In the preceding example, if the supported locales are en and ja, the user locale is determined to be en, since fr and de are not supported by the application and en has precedence over ja.
