Keeping current locale after logging out

[Antonio Sánchez]

At logging out, session is invalidated and redirected page is displayed in 
default language. 

Say: default language: Spanish; current language: English; logging out and 
resulted page is in Spanish, but should be English. . 

This is not working (code in action class):

    public String closeSession()  {
        Locale currentLocale = ActionContext.getContext().getLocale();
        request.getSession().invalidate();
        ActionContext.getContext().setLocale(currentLocale);
        return SUCCESS;
    }

How to maintain the current language?

Thanks.
