HTTP caching

The remote REST service for PUMA sets the Cache-Control HTTP header in the response to public for resources that are served without authentication, and to private for URIs that require authentication.

The expiration time is defined by the max-age directive in the same header and can be configured as a number in seconds within the wp.user.restservice.maxage environment entry of the remote REST service for PUMA enterprise application. This is called UserProfileRESTServlet in the WebSphere® Integrated Solutions Console. It defaults to the value 3600 seconds, that is equivalent to one hour.
