The limit is enforced and the request is ratelimited, i.e. a response with 429 HTTP status code is sent back to the client when the selected requests have reached the limit. |
RateLimitSelectCondition
RateLimitSelectCondition specifies the attributes within the traffic flow that can be used to select a subset of clients to be ratelimited. All the individual conditions must hold True for the overall condition to hold True.
