I would add this
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past

Hi, I got a solution for it....Add the following statement to every controller constructor,except the login page constructor. ........ $this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate, no-transform, max-age=0, post-check=0, pre-check=0"); $this->output->set_header("Pragma: no-cache");
