Example Requests

The following example shows how to change the rate limit settings of a CC protection rule. The project ID is specified by project_id and protection policy ID is specified by policy_id. The rule name is test55, the rate limit mode is IP-based rate limit, rate limit frequency is 10, the rate limit duration is 60s, and the protective action is verification code. The protection mode of the CC rule is advanced. The field type of the rate limit condition is the URL that contains /url. There is no subfield. Requests are counted only for the current WAF instance.
