This gives the client a hint, that they can consider the customer object valid for 300s = 5min. Proxies on the way are also allowed to cache the returned object. In practice one may make the maxAge depending on e.g. some average update frequencies and also set the "you need to always verify" flag via cc.setMustRevalidate(true).
