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 Resour ces

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 Ta gs” 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 cachingis not stored in the processing cache, but the ‘session’ cache.

S E S S I O N C A C H E

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.
