An application pool is a group of configuration settings that specify how one or more Web applications are routed to one or more work processes. InstallShield lets you create application pools and associate Web sites and virtual directories with those application pools. When you select an application pool in this view, you can configure the IIS settings that are associated with the application pool. Most of the properties are also configurable through the IIS Microsoft Management Console.

Application pools are available only on machines with IIS 6.0 or later installed.
