File proxy power-up is used to proxy any file through the server Google Tag Manager. This feature helps to load files from your domain instead of using third-party domains.
To set up file proxy power-up:
- Add the URL of the file that you want to proxy.
- Specify the sGTM path that should be used to proxy the file through the tagging server URL. For example, if your tagging server URL sgtm.example.com, and the sGTM path is /file.js. Then the file will be loaded from sgtm.example.com/file.js.
- Set maximum cache age.
