Azure WAF Custom Rule Samples and Use Cases

Re: the Important Custom Rule Concepts section;

The most important thing to mention about Custom Rules is that they are terminating. This means that if the logic of the rule is matched, all other rules stop processing, including the lower priority (higher number) Custom Rules, and both OWASP and Bot managed rulesets. This is the case regardless of the action of the rule

The documentation says this is not the case when the rule action is 'Log';
