when switching between pages inside the same application using
Executions.sendRedirect("other.zul");

when switching between applications using
Executions.sendRedirect("http://servername:8082/app2/main.zul");

however it works when reloading the same url
Executions.sendRedirect("http://servername:8081/app1/main.zul");
