I have 3.2r running and we are using Alfresco WCM in a slightly less traditional way. We are using the FSR to deploy the content to an XSAN repository that is read from by Endeca and WebSphere Commerce to retrieve the content. Launching the content works fine as it is still in Alfresco at this time. Once the FSR moves it to an external file store, how, if at all, would you expire it. Is the WCM functionality supposed to use the FSR to locate and remove content when it is no longer valid, or is the expire only meant to work if the content is running traditionally from the Alfresco WCM via the virtualization server?
