Return user to previous page after login?

Question

I have a controller called "Accounts" with the words "signin" and "signout".

The corresponding functions are as follows:

function signin()
{
    if (!empty($this->data)) 
    {
        //handle login
        ...
        //save login to session
        $this->Session->write('Account',  $data["Account"]);
        //redirect to previous page
        ???
    }
}

function signout()
{
    //delete login
    $this->Session->delete('Account');
    //redirect to previous page
    ??? 
}

If the user goes to accounts/signin, he first checks if the form has been submitted if(!empty($this->data)), if so, she registers them if he does not display the signing form. If they are successfully logged in, I want to redirect them to the page on which they were before the page with the signature.

What is the best way to do this?

AppController UserController,

AppController beforeFilter action

$referer = Router::url($this->url, true);
$this->Auth->loginAction = array('controller'=>'users','action'=>'login','?'=>['referer'=>$referer]);

UserController login action

if($this->Auth->login())
{
 $this->Session->setFlash(__('Logged in successfully !'));
$redirect = $this->request->query('referer');
if(!empty($redirect))
 {
   return $this->redirect($this->Auth->redirectUrl($redirect));
 }else{
    return $this->redirect($this->Auth->redirectUrl());                 
 }
}
