JSF，会话超时处理[复制]

Question

这个问题已经在这里有一个答案：

• Authorization redirect on session expiration does not work on submitting a JSF form, page stays the same 2个回答

我已经在服务器中配置我的会话超时，并添加了一个过滤器来处理会话超时。但是，当我试图把它重定向到登录页面，它不工作。我搜索网，但没有得到任何固体。我使用JSF ..我的代码

public class SessionTimeoutFilter implements Filter {

private String timeoutPage = "login.seam";
public void init(FilterConfig filterConfig) throws ServletException {
}
public void doFilter(ServletRequest request, 
  ServletResponse response, FilterChain filterChain) throws IOException,ServletException {
if ((request instanceof HttpServletRequest) 
   && (response instanceof HttpServletResponse)) 
{
    HttpServletRequest httpServletRequest = (HttpServletRequest) request;
    HttpServletResponse httpServletResponse = (HttpServletResponse) response;
    if (isSessionControlRequiredForThisResource(httpServletRequest)) {
        if (isSessionInvalid(httpServletRequest)) 
        {
            String timeoutUrl = httpServletRequest.getContextPath() 
           + "/" + getTimeoutPage();
            System.out.println("Session is invalid! redirecting to timeoutpage : " + timeoutUrl);
            httpServletResponse.sendRedirect(timeoutUrl);
            return;
        }
    }
}
filterChain.doFilter(request, response);
}

谁能告诉我什么我做错了什么？为什么不的sendRedirect响应
