Task IIS - Add Application Pool​

The IIS - Add Application Pool Task creates a new application pool in Internet Information Services (IIS). Application pools isolate web applications from one another for improved security, reliability, and performance.

To use IIS Tasks you need to create a Connection first. Click the Settings icon to open the Manage Connections dialog.
