Different ${pageContext.response.locale} from chrome and firefox

Question

In a JSP, i have:

<script type="text/javascript" src="<c:url value="/resources/js/library/validate_localization/messages_${pageContext.response.locale}.js"/>"></script>

to include validation messages for different locales ( messages_en.js ... messages_it.js ... etc etc )

In chrome it's everything ok, but in firefox, the browser try to include messages_en-US.js ... messages_it-IT.js .... how i can get always the same locale code in all browsers?

Thanks
