Detection approach

FlareSolverr data: URI navigation detected. The browser arrived from a data:text/html URI, which is FlareSolverr's unique technique for simulating POST requests via a hidden auto-submit form. Real users never navigate from data: URIs.

How this helps detect bots

Collect this signal alongside session context, request metadata, and other independent indicators. A single anomaly is a lead, not a verdict; corroborating anomalies make automated traffic more likely.

Legitimate traffic to consider

None. Human web users never navigate to websites from raw data: URI redirect forms.
