The newly introduced CacheControlStrategy interface enables CAE apps to apply cache control information to HTTP responses. The default implementation records the instant at which a requested resource expires and also provides access to the app's static cache control configuration. The CacheControlStrategy bean is used by a Spring MVC handler interceptor to send Cache-Control headers. The cache control information then may be used subsequently by CDNs or other HTTP caching proxy infrastructure.

The cache control defaults can be configured via bean type of the requested resource or url of the handler. The configuration prefix is "cae.cache-control". See javadoc of CacheControlConfigurationProperties for more details. The default configuration for the CAE live app which should be reviewed and adjusted to project needs.
