How to validate in Cloudflare

Cache

Check CF-Cache-Status in response headers.
Validate query/header variation.
Use Cache Analytics for trends.

WAF

Go to Security Events.
Filter by hostname/path.
Confirm rule ID and action.

Bot Management

Compare browser vs curl responses.
Use Bot Analytics if enabled on the zone.
