Servlet cache instance collection
A servlet cache instance is a location, in addition to the default shared dynamic cache, where dynamic cache can store, distribute, and share data. By using servlet cache instances, the applications have greater flexibility and better tuning of the cache resources. The Java™ Naming and Directory Interface (JNDI) name specified for the cache instance is mapped to the name attribute in the <cache-instance> tag in cachespec.xml.
