services/cache/iwk/menu - Menu
Default size: 2000, default lifetime: infinite, usage pattern: regular.
This cache stores WCM Menu entries. An entry comprises of the Content IDs associated
with a particular menu. The entries are retrieved and cached without applying security.
Whenever a user needs that menu’s results, their specific security will then be applied to
the cached results. A dynamic menu, which is one that is affected by the current user’s
context (e.g. based on categories in a users profile) will store a separate cache entry for
each different context. The cache entry will be cleared when a WCM Item is updated that
will affect this menu.

complex navigator might have multiple parent to child relationships (e.g. if siblings are
