Class ActionCounterEventAspect

java.lang.Object
  org.apache.avalon.framework.logger.AbstractLogEnabled
      org.apache.cocoon.portal.event.aspect.impl.ActionCounterEventAspect

All Implemented Interfaces:

Component, LogEnabled, Parameterizable, ThreadSafe, EventAspect

public class ActionCounterEventAspect
extends AbstractLogEnabled
implements EventAspect, ThreadSafe, Parameterizable

This aspect "disables" the back button of the browser and tries to avoid problems with the user browsing in multiple windows. This event attaches a unique number to each request. For each user only the current number is "active". Every request comming in containing an older number is disregarded and therefore ignored. WARNING: This aspect solves some problems while introducing new ones. Some features of the portal do NOT work when this aspect is used.
