According to the Istio doc: https://istio.io/docs/tasks/policy-enforcement/rate-limiting/

After applying the quota rule for conditional rate limits, rate limit should not apply to a logged in user. Log in as jason and repeatedly refresh the productpage. Now you should be able to do this without a problem.

However, we tested this in both local oc cluster up environment and remote OCP environment. Sometimes we still see RESOURCE_EXHAUSTED:Quota is exhausted for: requestcount. message after log in as jason

This Rate limit feature is not stable. there is a known upstream open issue: https://github.com/istio/istio/issues/8483

The performance of both Rate limit and Conditional Rate limit changes also takes 1-2 mins to be reflected from UI.
