I would like to update the conditional-rate-limit to be based on a match of the URL in the request.

I found these docs, https://istio.io/docs/reference/config/policy-and-telemetry/istio.policy.v1beta1/#Rule

But can't track down what the correct attribute would be to use

As a guess, I tried

apiVersion: config.istio.io/v1alpha2
kind: rule
metadata:
  name: quota
  namespace: istio-system
spec:
  match: match(request.uri, "/A/B/93*") == true
  actions:
  - handler: handler.memquota
    instances:
    - requestcount.quota

But that errors with

Unable to compile match condition expression: 'unknown attribute request.uri', rule='quota.rule.istio-system',
enter code here

Thanks, Brent
