Blocking rule guidance
These examples are derived from the canonical directory action and match scope. Review site compatibility before enforcement.
- Adblock / uBlock
||assets.customer.io^$third-party
Third-party blocking is contextual. It is intentionally not represented as an unconditional DNS or hosts rule because DNS cannot distinguish first-party from third-party requests.
