WCM Expiring Strategies
Like Caching Strategies, a Server's default Expiring strategies can be set in connect.cfg. Custom Expiring parameters can also be set in "Connect" tags and URL requests to override a Server's default Expiring strategies. Note that if Basic Caching is used as your default Web Content Cache, Custom Expiring cannot be used.
In most cases the Expiry schedule is based around how often the source Content is updated. So, if the source Content is updated hourly, then each Cache would be expired hourly. If the source Content is updated daily, then each Cache would be expired daily.
Beyond these examples, a different Expiry schedule would be used. If your Web Pages were only updated weekly, or monthly, you would still schedule your caches to expire daily. Otherwise, when your source content was updated, it could take up to a week for it to appear on your Site.
Data can also be flushed (removed) from the cache while the Web Content Management application is still running via the Web Content Management Administration Interface This frees up memory or disk space (or both), and causes the Web Content Management application to retrieve fresh versions of any required data.
Caching Expiries versus Workflow Expiries
The Expires parameter in a Web Content Management Workflow is not related to the Expires parameter in Web Content Management Caching. A Web Content Management page that is set to expire at midnight as part of a Workflow will only do so if it hasn't already been saved in a Web Content Management Cache. The Web Content Management page will remain in the Web Content Management cache until expired by the Web Content Management application regardless of the Expires setting in a Web Content Management Workflow.
