using redirect() help?

It won't work in this way, because when you click on the link, the the app lives the 'catalog' controller, and you will refresh the 'site' controller. Try to save the current page in session_flashdata in the 'catalog':

function site() {
parent::Controller();
$this->session->set_flashdata('last_url', uri_string());
}

and try this in the site/set_language:

function set_language(){
redirect($this->session->flashdata('last_url');
}
