> We should evaluate adding a new "cache" dsl that can be used with all cache components in Camel. A default implementation may use also caffeine, included in camel-core.
> A possible usage example may be:
> {code}
> from("xxx")
> .cache().on("${header.yyy}").ttl(600000) // caches the body
>   .to("http4://a-service-that-makes-me-pay-for-each-request.com/api/expensive-endpoint")
>   .transform().zzz()
>   .to("http4://or-a-service-that-i-can-call-few-times-a-day.com/api/limited-endpoint")
>   .unmarshal()
> .endCache()
> {code}
> It should be also useful to protect internal services when using Camel e.g. as a api-gateway (almost what hystrix does in case of failure of the target host).
