demo: waf custom rule → geo block (US)

a waf custom rule blocks any request from a US ip address on this endpoint. if you are in the US, you'll see the branded 403 block page. if you are outside the US, the endpoint returns 200 with your detected country. test both by hopping on a vpn.

# trigger the geo rule

the button below fires fetch('/api/geo-check'). the waf rule also matches on the raw path /waf-geo-block, so a full-page navigation there will show the branded 403 directly.

navigate to /waf-geo-block
click a button…

# or from your terminal

# from a US ip → 403 branded block page
curl -i "https://rhocfsandbox.com/api/geo-check"

# from a non-US ip → 200 with detected country
curl -s "https://rhocfsandbox.com/api/geo-check" | jq
