Web content cache configuration

We can tailor the caching behavior of the web content environment by changing configuration settings such as the default cache type and expire settings.

You define and manage web content cache options in the WCM WCMConfigService service.

Set the default web content cache type

The default web content caching environment for the web content server is specified by the following properties:

• connect.businesslogic.defaultcache

• connect.moduleconfig.ajpe.contentcache.defaultcontentcache

Parameter	defaultcache value	defaultcontentcache value
No caching:	false	None
Basic cache:	true	Not specified
Site caching:	false	Site
Session caching:	false	Session
User caching:	false	User
Secured caching:	false	Secured
Personalized caching:	false	Personalized

Additional default web content cache parameters

Web content cache configuration settings are specified by the following properties in the WCM WCMConfigService service.

Cache Type	Properties
Basic cache:	connect.businesslogic.defaultcacheexpires connect.businesslogic.defaultcache
Advanced cache: All	connect.moduleconfig.ajpe.contentcache.defaultcontentcache connect.moduleconfig.ajpe.contentcache.contentcacheexpires
Advanced cache: Session cache only	connect.sessioncacheconfig.memcachesize

Cache Property	Details
contentcacheexpires	Default expiry for all advanced caches. It can be either a relative period or an absolute date and time.
defaultcache	If true, basic caching is enabled. If false or missing, advanced caching is enabled.
defaultcacheexpires	Default expiry for the basic cache. It can be either a relative period or an absolute date and time.
defaultcontentcache	If the advanced cache is enabled, the default advanced cache is set here.
resourceserver.browserCacheMaxAge	Define the maximum time an item will be stored in a web browser cache.
resourceserver.maxCacheObjectSize	Define the maximum size of objects that can be cached in kilobytes. By default this is set to 300.

Cache expire time formats

When setting the cache expire settings listed in Table 3, we can specify either a relative time, or absolute time:

• REL {integer-value}{units}

• ABS {date-format-string}

{units} =

• d|D for days

• m|M for months

• s|S for seconds

• h|H for hours

{date-format-string} =

• Mon, 06 Nov 2000 09:00:00 GMT

• Monday, 06-Nov-00 09:00:00 GMT

• Mon Nov 6 09:00:00 2000

• 6 Nov 2000 9:00 AM

The last two formats assume GMT.

Examples:

• contentcacheexpires="REL 300S"

• contentcacheexpires="ABS Mon, 06 Nov 2000 09:00:00 GMT"
