Frequently Asked Questions
What does Referrer-Policy control?
It controls how much referrer information the browser includes when navigating to another resource.
Which policy is commonly recommended?
strict-origin-when-cross-origin provides a practical balance between analytics compatibility and reduced cross-origin disclosure.
Can the tool inspect any website automatically?
No. Browser cross-origin restrictions prevent reliable remote header inspection, so the policy value must be pasted into the tool.
