To enable the HTTP keep-alive response header

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 HTTP Response Headers.

3. On the HTTP Response Headers page, in the Actions pane, click Set Common Headers.

4. In the Set Common HTTP Response Headers dialog box, select the Enable HTTP keep-alive check box and then click OK.

Command Line

To enable the HTTP keep-alive header, use the following syntax:

appcmd set config /section:httpProtocol /allowKeepAlive:true | false

By default, the HTTP keep-alive header is enabled, but you can disable it by setting allowKeepAlive to false. For example, to disable the HTTP keep-alive header, type the following at the command prompt, and then press ENTER:

appcmd set config /section:httpProtocol /allowKeepAlive:false

For more information about Appcmd.exe, see Appcmd.exe (IIS 7).
