Rate limiting CDN

[VishnuRa5]

I am trying to implement rate limiting at the CDN level in AEMaaCS.

I am testing this in an RDE using rules referenced in the Adobe documentation. However:

• The rate limit is not being triggered

• I tried multiple variations

• I expected a 429 Too Many Requests response, but never received it

• Is 429 the default HTTP error returned when a CDN rate limit is exceeded?

• Is there already a default rate limit applied at the CDN layer in AEMaaCS?

kind: "CDN"
version: "1"
data:
  trafficFilters:
    rules:
    - name: limit-requests-client-ip
      when:
        reqProperty: tier
        matches: "author|publish"
      rateLimit:
        limit: 60
        window: 10
        penalty: 300
        count: all
        groupBy:
          - reqProperty: clientIp
      action: block

Any suggestions for fine-tuning the rate-limit configuration, and is there a recommended way to test it?

Thankyou very much !!
