General rules considerations

When setting up rules for Cloudlets, keep the following in mind:



Rule evaluation

  • Cloudlets rules are evaluated from first to last, and the first match wins.
  • As a best practice, order your rules so that the ones that will exclude the most incoming requests are towards the top of the list.
  • If an incoming request doesn't trigger a rule, then the Cloudlet does not execute. The request is then evaluated against the property rules.
  • Cloudlets policies do not have child rules.
  • You can add 5000 rules to a Cloudlets policy.
  • **Note:** If your rules aren't working as expected before the 5000 limit, try running the [Policy Analysis Tool](doc:use-policy-analysis-tool) first. Contact support if you can't resolve the issue. You may have hit a cost limit.

    Match rules

  • All match types support negation.
  • If you have multiple match criteria in a rule, the criteria are all part of a single logical AND operator.
  • ELSE statements aren't supported.
  • Versioning

  • When you create a new policy, the system automatically creates version 1 of the policy. This version is empty: it has no description or rules.
  • When cloning a policy, version 1 of the new policy includes rules from the most recent version of the cloned policy.
  • Character limitations

    You can't use these characters with Cloudlets rules:
