Create an Application Pool (IIS 7)31 out of 52 rated this helpful

Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista

Application pools isolate sites and applications to address reliability, availability, and security issues. You should consider creating applications pools for any one ofthe following reasons:

To group sites and applications that run with the same configuration settings.

To isolate sites and applications that run with unique configuration settings.

To increase security by using a custom identity to run an application.

To prevent resources in one application from accessing resources in another application. For example, ISPs might create individual application pools for eachcustomer's sites and applications. Separating customer content in this manner can prevent one customer's resources from accessing resources on anothercustomer's site, even though both customers' sites are on the same Web server.

To improve performance by separating unstable applications from wellbehaved applications.

Prerequisites

For information about the levels at which you can perform this procedure, and the modules, handlers, and permissions that are required to perform thisprocedure, see Application Pools Feature Requirements IIS 7.

Exceptions to Feature Requirements

None

To create an application pool on a Web server

You can perform this procedure by using the user interface UI, by running Appcmd.exe commands in a commandline window, by editing configuration filesdirectly, or by writing WMI scripts.

User Interface

To use the UI

1. Open IIS Manager. For information about opening IIS Manager, see Open IIS Manager IIS 7.

2. In the Connections pane, expand the server node and click Application Pools.

3. On the Application Pools page, in the Actions pane, click Add Application Pool.

4. On the Add Application Pool dialog box, type a friendly name for the application pool in the Name box.

5. From the .NET Framework version list, select the version of the .NET Framework required by your managed applications, modules, and handlers. Orselect No Managed Code if the applications that you run in this application pool do not require the .NET Framework.

6. From the Managed pipeline mode list, select one of the following options:

Integrated, if you want to use the integrated IIS and ASP.NET request processing pipeline.

Classic, if you want to use IIS and ASP.NET requestprocessing modes separately. In classic mode, managed code is processed by usingAspnet_isapi.dll instead of the IIS7 integrated pipeline.

7. Select Start application pool immediately to start the application pool whenever the WWW service is started. By default, this is selected.

8. Click OK.

Command Line

To add an application pool to a Web server by using default settings, use the following syntax:

appcmd add apppool /name: string

The variable string is the name that you want for the application pool. For example, to add an application pool named Marketing, type the following at thecommand prompt, and then press ENTER:

appcmd add apppool /name: Marketing

By default, IIS adds an application pool that runs in integrated mode and uses .NET Framework version 2.0. If you want to add an application pool that runs adifferent version of the .NET Framework or that uses classic mode, you can specify the .NET Framework version with the /managedRuntimeVersion attributeand the managed requestprocessing mode with the /managedPipelineMode attribute.

To add an application pool to a Web server by using settings different from the default settings, use the following syntax:

appcmd add apppool /name: string /managedRuntimeVersion: .string /managedPipelineMode: Integrated | Classic

The variable namestring is the name that you want for the application pool. The variable managedRuntimeVersionstring is the version of the .NET Frameworkthat you want the application pool to run. When you want to run a specific version of the .NET Framework, specify the value formanagedRuntimeVersionstring as v1.0, v1.1, or v2.0, or leave the value blank if you do not want to run managed code in the application pool. For example,to add an application pool that does not run managed code and that uses classic mode, type the following at the command prompt, and then press ENTER:

appcmd add apppool /name:Marketing /managedRuntimeVersion: /managedPipelineMode:Classic
