Render Request Processing

The request from the client is encapsulated in a RenderRequest object. The portlet uses this object to access information about the request that was received from the client by the Portal Server. Typically, the current portlet mode and request parameters included in the incoming request is the information that is accessed. The portlet’s response is encapsulated in a RenderResponse object. Portlet use this object to set the content type of the response and send their portlet content to the portlet container.

Each request object is valid only within the scope of a particular processAction() or render() method call.
