<%@ page import="org.apache.commons.codec.CharEncoding" %>

<%@ page import="java.net.URLEncoder" %>

<%@ page import="java.util.Arrays" %>

<%@ page import="java.util.List" %>

String user = (String)session.getAttribute("loginUser");

String invalidUserPage = "invalidUser.jsp";

String loggerPage = "logger.jsp";

// Define a whitelist of trusted pages

List<String> trustedPages = Arrays.asList("invalidUser.jsp", "logger.jsp");

if(user == null) {

String failReason = (String)request.getAttribute("failReason");

if (trustedPages.contains(invalidUserPage)) {

%>

<jsp:forward page="invalidUser.jsp">

<jsp:param value="<%=failReason%>" name="failReason" />
