Wie kann ich Benutzer nach der Laravel-Anmeldung zurück zu ihrem ursprünglichen Ziel umleiten?

return redirect()->intended('defaultpage');

// redirect to "/login" and store the URL in session
if (Auth::guest()) {
    return redirect()->guest('login');
}

// redirect back to intended page or default if not available
if (Auth::attempt(['email' => $email, 'password' => $password])) {
    return redirect()->intended('defaultpage');
}

// redirect to "/login" and store the URL in session
Route::filter('auth', function() {
    if (Auth::guest()) {
        return Redirect::guest('login');
    }
});

// redirect back to intended page or default if not available
if (Auth::attempt(['email' => $email, 'password' => $password])) {
    return Redirect::intended('defaultpage');
}

Route::filter('auth', function() {
    if (Auth::guest()) {
        Session::put('redirect', URL::full());
        return Redirect::to('/login');
    }
    if ($redirect = Session::get('redirect')) {
        Session::forget('redirect');
        return Redirect::to($redirect);
    }
});

// login action
public function post_login()
{
    if (Auth::attempt($credentials)) {
        return Redirect::to('logged_in_homepage_here');
    }

    return Redirect::to('login')->with_input();
}
