Exclude a page from a filter in Java

I have done a Filter in Java, but I want to exclude the ForgotPassword.xhtml file besides the index.xhtml, where do I have put the xhtml name to exclude it?

public class LoginFilter implements Filter {

.........

public void destroy() {

}

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

      ...................

      if (noProteger(urlStr)) {
        chain.doFilter(request, response);
        return;
      }

      if (usuarioBean == null || !usuarioBean.estaLogeado()) {
        res.sendRedirect(req.getContextPath() + "/index.xhtml");
        return;
      }

      chain.doFilter(request, response);
}

public void init(FilterConfig fConfig) throws ServletException {

}

private boolean noProteger(String urlStr) {    

    if (urlStr.endsWith("index.xhtml"))
        return true;
    if (urlStr.indexOf("/javax.faces.resource/") != -1)
        return true;
    return false;
}

}

If you all could help me, I will be so thankful
