After page expiration (session-timeout), give auto refresh to login screen

I'm developing an application in JSF, where I have a login screen that has a page filter as a business rule, where the user can access the other pages if they start a session.

My application has a certain Timeout, which when hit, I would like the page to self-redirect and go straight to my login page, but what happens in practice is that I need to press Ctrl + F5 to refresh and then go to the login screen.

Below the code in xhtml:

<ui:define name="cont_principal">   

    <div class="conteudo">    
       <div id="container">

        <p:messages class="ui-messages-mensagem" id="msg" showDetail="true" autoUpdate="true" closable="true"/>       
        <br></br>

        <div id="titulo_page">Área Restrita</div>        
        <div id="login_box">
        <div id="logo_login">
        <h:graphicImage value="/RESOURCES/icons/login/icons_login.png" id="login_title" />
        </div>
        <div id="titulo_login">Login</div>
        <h:form id="formLogin" enctype="multipart/form-data">  

        <p:panelGrid columns="2" class="withoutBorder" >
        <h:outputLabel id="info_login"> <h:graphicImage url="/RESOURCES/icons/login/icons_user.png" class="login_icon" /></h:outputLabel>
        <p:inputText value="#{login.usuario}" id="login" class="input-login"/>             

        <h:outputLabel id="info_senha"> <h:graphicImage url="/RESOURCES/icons/login/icons_password.png" class="login_icon" /></h:outputLabel>
        <p:password value="#{login.password}" id="senha" class="input-login"/>   

        <p:watermark for="login" value="Usuário"/>   
        <p:watermark for="senha" value="Senha" />        

        </p:panelGrid>                       
        <br/>

         <div>
         <p:commandButton id="btnEntrar" icon="ui-icon-unlocked" value="Entrar"
        action="#{login.logarNoSistema}" />                

        </div>  

How is my Filter:

@Override
public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain)
        throws IOException, ServletException {

     HttpServletRequest request = (HttpServletRequest) req;
     HttpServletResponse response = (HttpServletResponse) resp;
     HttpSession session = request.getSession();

     FacesContext context = FacesContext.getCurrentInstance();

     String loginURI = request.getContextPath() + "/RESOURCES/paginas/login.xhtml";

     boolean loggedIn = session != null && session.getAttribute("user") != null;
     boolean loginRequest = request.getRequestURI().equals(loginURI);
     boolean resourceRequest = request.getRequestURI().startsWith(request.getContextPath() + ResourceHandler.RESOURCE_IDENTIFIER);
     boolean resourceRequestCSS = request.getRequestURI().contains("/RESOURCES/css");
     boolean resourceRequestIcons = request.getRequestURI().contains("/RESOURCES/icons");            

     if (loggedIn || loginRequest || resourceRequest || resourceRequestCSS || resourceRequestIcons) {
         chain.doFilter(request, response);

     } else {
         response.sendRedirect(loginURI);    }          
  }

Filter in web.xml:

<filter>
    <filter-name>filtro</filter-name>
    <filter-class>br.com.map.filter.filtroURL</filter-class>
</filter>

<filter-mapping>
    <filter-name>filtro</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

And finally I'm tempted to use PhaseListener :

private String getLoginPath() {
    return "/RESOURCES/paginas/login.xhtml";
}

@Override
public void afterPhase(PhaseEvent arg0) {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    if (!facesContext.getPartialViewContext().isAjaxRequest() || facesContext.getRenderResponse()) { // not ajax or too late
        return;
    }

    HttpServletRequest request = HttpServletRequest.class.cast(facesContext.getExternalContext().getRequest());

    if (request.getDispatcherType() == DispatcherType.FORWARD && getLoginPath().equals(request.getServletPath())) { // isLoginRedirection()
        final String redirect = facesContext.getExternalContext().getRequestContextPath() + request.getServletPath();
        try {
            facesContext.getExternalContext().redirect(redirect);
            // facesContext.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, 
            //      "Sessão Expirada", "Entre novamente com seu login e senha"));

        } catch (IOException e) {

        }
    }
}
