Own CDN
Own CDN helps first-party cookies last longer by making the custom subdomain used for sGTM hosting by Stape or Stape Gateway use the same IP as your website.
How to access Own CDN
Own CDN is available on all Stape plans. You can enable it in the Stape app in your container or gateway settings.
How Own CDN works
Own CDN lets your server-side tracking custom subdomain use the same IP address as your website. It helps Safari and other browsers with ITP avoid shortening first-party cookie lifetime because of an IP mismatch.
Benefits of Own CDN
- Longer first-party cookie lifetime. Own CDN helps first-party cookies last longer, which is important in browsers with ITP, where cookies can be cut to 7 days.
- Stable attribution and conversion tracking. When cookies stay active for longer, your setup can connect conversions to earlier visits across a longer period. This helps you see a complete path to conversion and reduce unattributed results.
Make your cookies last longer
If browsers shorten the cookies' lifespan because your tagging subdomain uses a different IP than your website, Own CDN fixes that. It makes your tracking subdomain use the same IP as your site, which helps first-party cookies last longer.
