Secure cookie implementation

SameSiteCookieMiddleware.php that implements this feature but somehow not working for me.

	protected function setSameSiteCookie() {
		$cookieParams = $this->request->getCookieParams();
		$secureCookie = ($cookieParams['secure'] === true) ? 'secure; ' : '';
		$policies = [
			'lax',
			'strict',
		];
		// Append __Host to the cookie if it meets the requirements
		$cookiePrefix = '';
		if($cookieParams['secure'] === true && $cookieParams['path'] === '/') {
			$cookiePrefix = '__Host-';
		}
