# Eliminating cold start problem

> If there are no HTTP requests for a certain amount of time (the default is 20 minutes), then IIS suspends the application pool. After that, when a new request comes in, a startup delay is observed because the worker process needs to restart the application pool, load the .NET environment, compile and initialize your code, and finally serve the request. This is a so-called _cold start_.

To avoid the suspension of the Customer's Canvas application pool, perform the following steps:

1. Install the Application Initialization role. In the **Add Roles and Feature Wizard** of Windows Server 2012 and higher, select the **Application Initialization** check box.

2. Enable the Always Running mode. In IIS Manager, right-click the Customer's Canvas application pool, and then click **Advanced Settings**. Set the **Start Mode** option to `AlwaysRunning` and **Idle Time-out (minutes)** to `0`.

    In Windows Server 2012, you also need to set **Start Automatically** to `True`. Note, this setting was removed in Windows Server 2012 R2.

3. Enable the auto-start provider and application preload. You can perform this step through the `%WINDIR%\System32\inetsrv\config\applicationHost.config` file as follows:

    1. Add a `<serviceAutoStartProviders>` element to the `<system.applicationHost>` node to register `CcAutoStartProvider`.

        ```xml
        <serviceAutoStartProviders>
            <add name="CcAutoStartProvider"
                 type="Aurigma.DesignEditor.CustomersCanvasInitialization, Aurigma.DesignEditor" />
        </serviceAutoStartProviders>
        ```

    2. Locate the entry for the Customer's Canvas site under the `<sites>` node, enable the application preload, and register the auto-start provider for this site.

        ```xml
        <sites>
            <site name="CustomersCanvas" id="1" serverAutoStart="true">
                <application path="/"
                             applicationPool="CustomersCanvas"
                             preloadEnabled="true"
                             serviceAutoStartEnabled="true"
                             serviceAutoStartProvider="CcAutoStartProvider">
                </application>
            </site>
        </sites>
        ```

After you have done all these changes, type `iisreset` at the command prompt to restart IIS.
