public class RequestCachingConnector
extends org.springframework.extensions.webscripts.connector.AlfrescoConnector

Extension of the AlfrescoConnector to provide GET method request caching for the lifetime of a single page request.

If a GET request is within the context of an executing page with a valid RequestContext, then the request response is cached keyed on the URI.

The cache is examined for further GET requests. The cache is then destroyed when the RequestContext is discarded at the end of the page processing lifecycle. This removes the need for complex cache management and concerns over stale data between page requests - the cache is simply used to provide identical data to discrete components that execute within the context of the same page without causing multiple requests.
