In simple terms, caching refers to being able to cache API response data. In the most basic scenario, this is the ability to cache the response of a downstream service call. For example, when a second (similar) call occurs, the downstream service won't have to be invoked as the response is already cached. This known as a Response Cache.
This capability can be extremely useful when preventing a large number of similar calls translating to an even larger number of downstream service calls. Caching response data means not only faster response times, but also avoiding unnecessary downstream service calls. However, conditions will be required in order to prevent consumers from receiving outdated/irrelevant data.
