# PAC file with registry setting

In this proxy configuration, the Proxy Auto-Configuration \(PAC\) file can be configured in Password Reset Windows Application registry settings.

The name of the registry setting enables the proxy via PAC file is **UseProxyAutoConfigScript**. The PAC script location \(URL\) can be provided in the **ProxyServer** setting. The reference configuration is provided as shown in the following image:\[Omitted image "pac-registry-settings2.png"\] Alt text: PAC registry settings

## Registry setting to configure proxy via PAC

-   ProxyEnable – <true>

    Enables the proxy on application level.

-   ProxyServer – <PAC file URL>

    Initialize the PAC file location here.

-   UseProxyAutoConfigScript – <true>

    If set to true, it indicates that the address provided in the **ProxyServer** registry setting is PAC script.


## How it works

The PAC file provided in the **ProxyServer** registry setting is used to get the actual target proxy server address for a URL \(In this case, the ServiceNow instance\) based on the PAC file script configuration. The PAC file script must return a valid Proxy server address for a provided ServiceNow URL to make the application work.

The target proxy address is cached for a URL in the machine. The caching behavior is applicable for the browsers as well. The ServiceNow® Password Reset Windows Application behaves the same as the Internet Explorer browser. That is, if the URL is accessible via a browser, then it's accessible via the app as well.

**Note:** It is not necessary to configure the proxy setting in Internet Explorer as the APP is reading the PAC file script via a registry.
