/**
 * Interface for web-based locale resolution strategies that allows for
 * both locale resolution via the request and locale modification via
 * request and response.
 *
 * <p>This interface allows for implementations based on request, session,
 * cookies, etc. The default implementation is AcceptHeaderLocaleResolver,
 * simply using the request's locale provided by the respective HTTP header.
 *
 * <p>Use RequestContext.getLocale() to retrieve the current locale
 * in controllers or views, independent of the actual resolution strategy.
