ATG Scenarios can employ slots to display targeted variable content on a page. You can learn more about slots in the Creating Scenarios chapter of the ATG Personalization Guide for Business Users and the Using Slots chapter in the ATG Personalization Programming Guide. One of the ATG Portal baseline gears, the Slot Gear, lets you display a slot’s content in a portal page. This section describes how, in an ATG Portal application, you can use a slot to display different gears based on targeting rules.
