Page display changed when i use filters in JSF

I am using following filter to control access to all pages in JSF 2.0 using GlassFish as application server. The problem is that with this code although filter works fine and user are redirected to log.xhtml if they try to acess anyother page directly but the login.xhtml does not look good as it should be which you can see below. However if i remove the sendRedirect statement and replace it with chain.doFilter statement, then the page displays in the same way as it should be looking nice and good however filtering does not work obviously. How can I fix this problem?


LoggingFilter.java

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws ServletException, IOException {
HttpServletRequest req = (HttpServletRequest) request;
LoginBean auth = (LoginBean) req.getSession().getAttribute("loginBean");




if ((auth != null && auth.isLoggedIn()) || req.getRequestURI().endsWith("/login.xhtml")) {
// User is logged in, so just continue request.
HttpServletResponse httpResponse = (HttpServletResponse)response;
httpResponse.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
httpResponse.setHeader("Pragma", "no-cache"); // HTTP 1.0.
httpResponse.setDateHeader("Expires", 0); // Proxies.
chain.doFilter(request, response);
} else {
// User is not logged in, so redirect to index.
HttpServletResponse res = (HttpServletResponse) response;
res.sendRedirect(req.getContextPath() + "/faces/login.xhtml");
//FacesContext.getCurrentInstance().getExternalContext().dispatch("/login.xhtml");
//chain.doFilter(request, response);
}
}
