services/cache/iwk/module
Default size: 2000, default lifetime: infinite, usage pattern: regular.
This cache is used for WCM Basic caching. See the InfoCenter on setting up Basic
caching. The Basic cache stores the entire response. The key is based only on the URL
so all users will see the same response.

services/cache/iwk/processing – Advanced and Resources
Default size: 2000, default lifetime: 1 month (configurable), usage pattern: regular.
This cache stores the binary MIME for file and image resources in WCM. The maximum
size of resources to store is set in the WCMConfigService.properties file as the property
resourceserver.maxCacheObjectSize (in kb). Resources over this size are not cached
and are streamed directly to the response. The expiry is set in the same file as:
resourceserver.cacheExpiryDate. The cache entry will be cleared when that resource is
updated.
This cache also stores page data if WCM Advanced caching is enabled. See the
InfoCenter for enabling WCM Advanced caching. The processing cache stores
advanced caches for the following types:
•
Site: Similar to “Basic” Caching except that “Connect Tags” are processed each time.
•
User: Stores a copy of an item in the cache for each user
•
Secured: Users that belong to the same groups will access the same cached items
•
Personalized: Users who have selected the same personalization categories and
keywords, and who belong to the same Group, will access the same cached items
NOTE that the ‘session’ option for Advanced caching is not stored in the processing
cache, but the ‘session’ cache.

services/cache/iwk/session - Session
Default size: 2000, default lifetime: infinite, usage pattern: regular.
This cache stores the page data for when session advanced caching is enabled. See the
InfoCenter for enabling WCM Advanced caching.
