 `static fromResponse(Response $response, string $refUri) : Cookies` | Create a `Cookies` instance from a response and the request URI. Parses all `Set-Cookie` headers, maps them to the URI, and aggregates them.
-`addCookie(string|SetCookie $cookie, string $refUri = null) : void` | Add a cookie, mapping it to the given URI. If no URI is provided, it will be inferred from the cookie value's domain and path.

-`getAllCookies(int $retAs = self::COOKIE_OBJECT) : array|string`    | Retrieve all cookies. Returned array will have either `SetCookie` instances (the default), strings for each `Set-Cookie` declaration, or a single string containing all declarations, based on the `COOKIE_*` constant used.
