Creating an Application Pool

Applies To: Windows Server 2003, Windows Server 2003 with SP1

When you run IIS 6.0 in worker process isolation mode, you can group Web applications into application pools. An application pool is a grouping of URLs routed to one or more worker processes that share the same configuration. Application pools allow you to apply specific configuration settings to groups of applications and the worker processes servicing those applications. Any Web site, Web directory or virtual directory can be assigned to an application pool.

By creating new application pools and assigning Web sites and applications to them, you can make your server more efficient and reliable. In addition, your other applications are always available, even when the applications in the new application pool terminate.

For more information about creating application pools and configuring worker processes, see Creating Application Pools in IIS 6.0, Configuring Application Pool Identity with IIS 6.0, and Running IIS 6.0 as an Application Server.
