Edit ASP Settings (IIS 7)

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

IIS 7 provides default settings for ASP applications, but you can change those settings as needed. For example, you may want to enable client-side debugging on a test server to aide in troubleshooting issues during a test pass.

Prerequisites

For information about the levels at which you can perform this procedure, and the modules, handlers, and permissions that are required to perform this procedure, see ASP Settings Feature Requirements (IIS 7).

Exceptions to feature requirements

  • None

To configure ASP settings

You can perform this procedure by using the user interface (UI), by running Appcmd.exe commands in a command-line window, by editing configuration files directly, or by writing WMI scripts.

User Interface

To Use the UI

  1. Open IIS Manager and navigate to the level you want to manage. For information about opening IIS Manager, see Open IIS Manager (IIS 7). For information about navigating to locations in the UI, see Navigation in IIS Manager (IIS 7).

  2. In Features View, double-click ASP.

  3. On the ASP page, edit settings as necessary.

  4. When finished, click Apply in the Actions pane.
