Abstract: Embodiments relate to preview serving of content previews from a preview service for a component having associated content. A filter of a layered preview service executing on a processor receives a request from a client consumer for a feed from the component. The filter identifies a content reference returned by the component in response to the request for the feed. The filter establishes an association between the content reference and a user identifier of the client consumer as an authorization record. A preview service receives a preview request including the user identifier and a content identifier. The authorization record is checked to determine whether the content identifier matches the content reference for the user identifier. A content preview of the associated content as identified by the content identifier is served based on determining that a match exists.
