if (sesion == null) {
request.getSession();
System.out.println("session is null");
} else {
Object id = sesion.getAttribute("id");
Object test = sesion.getAttribute("test");
if (id == null) {
sesion.setAttribute("id", request.getRemoteAddr());
}
if (test == null) {
sesion.setAttribute("test", "test");
}
System.out.println("test:id " + sesion.getAttribute("id"));
