请回答我的问题。我没有得到满意的答复

问题是：“如何防止在cakephp中注销后访问访问的页面？”

在筛选前的AppController中提前感谢

：

// Check if the user is logged in
if (isset($this->Auth->user())) {
    // Save the visited page in session
    $this->Session->write('VisitedPages.', $this->here());
// If the user is not logged in
} else {
    // If the user has logged out and visited the page before
    if (isset($this->Session->read('VisitedPages.'.$this->here()))) {
        $this->redirect('/errorPage');
    }
}
