Arbortext PE Request Manager Dynamic Components
There are three major kinds of Dynamic Components: Cache Managers, Queue Managers, and Request Handlers. These objects are initialized when the Arbortext PE Request Manager is loaded and initialized by its servlet container. When the Arbortext PE Request Manager receives a request, it passes the request to each component in turn, asking the component to process the request and produce a response. If a component indicates that it cannot do so, the Arbortext PE Request Manager continues with the next component. When a component produces a response, the Arbortext PE Request Manager ends the scan and returns the response to the client.
Other dynamic Arbortext PE Request Manager components are described in Internal Components of Arbortext Publishing Engine.
