This is one of three actions used to provide caching requirements.
The Retrieve Cache action inserts a fragment of XML data into the FactBase from the cache.
Three parameters are required. The first is the location in the FactBase under which to place the retrieved data (to location), the second is a string value specifying the id (or key) under which the data is cached (cache id), and the third indicates whether the data is currently stored in the application cache or the users session cache (scope). This final parameter must contain one of the two values 'session' or 'application'.
Both the cache id and scope values can be determined dynamically using XPaths if required.
