How to use Referrer-Policy analyser
Identify the effective recognised Referrer-Policy token and explain its cross-origin behavior. The check runs when you submit the form. Its inputs are processed in this browser.
How the check works
Comma-separated policy tokens are checked against the recognised set. The last recognised token is selected, following the header fallback mechanism.
The Overview tab explains the findings. Measured data lets you search individual fields and values, while JSON report shows the complete export. Export JSON to retain a baseline, or print the findings for your own records. Review the report before sharing it: browser characteristics, token claims, and file names can reveal information about your setup.
Read the result in context
Policies control which referrer information may be sent on requests. strict policies suppress referrers on a downgrade; unsafe-url can expose a full referrer path across origins.
Understand the limits
Element-level policies, browser defaults and navigation conditions can affect actual requests. This is a configuration explanation, not a traffic capture.
