The browser hits the origin's endpoints at the rate you set, with status codes spread across 2xx, 4xx and 5xx. Switch to the gateway console and you get real curves and logs instead of an empty panel.
Hit one endpoint hard. Each square is one request, coloured by outcome: green reached the origin, amber came back 429, magenta was blocked by the gateway. You can see the exact request where the rule kicks in.
Requests each path below and works out whether the response came from the origin or from the gateway. The origin stamps every response with X-Demo-Backend. If that header is missing, the request never reached it.
Every request this page makes, newest first.
