Tag: eMarketingSpotCache

You can include the wcf:eMarketingSpotCache tag within an e-Marketing Spot JSP fragment to indicate that the JSP fragment is to be dynamically cached. This tag dynamically sets dependency IDs for e-Marketing Spot cache entries.

When the wcf:eMarketingSpotCache tag is used, the class for this tag dynamically sets the dependency IDs to invalidate the cached e-Marketing Spot JSP fragment when the e-Marketing Spot definition changes. The e-Marketing Spot definition changes whenever the content (marketing content, products, categories) or web activities that are associated with the e-Marketing Spot changes. The dependency IDs are set for the e-Marketing Spot (ID or name). Dependency IDs can also be set for the data (catalog entry, category, content) that is being displayed within an e-Marketing Spot.

If the parent page is being cached, the dependency IDs are set on the parent page cache entry
If the parent page is not being cached, the dependency IDs are set on e-Marketing Spot JSP cache entry

If you want to set dependency IDs for the content, catalog entries, or categories that display within an e-Marketing Spot, you must include the appropriate tag attribute. The value for the tag attribute should match the names that are issued by any database invalidation triggers. The value for the tag attribute should also match the names that are defined within the cachespec.xml for the e-Marketing Spot cache entry. For about e-Marketing Spot caching, see Overview of e-Marketing Spot JSP caching based on activity behavior.
