postProcessFirewallManagerRuleGroups property
The last set of rules for AWS WAF to process in the web ACL. This is defined in an AWS Firewall Manager WAF policy and contains only rule group references. You can't alter these. Any rules and rule groups that you define for the web ACL are prioritized before these.
In the Firewall Manager WAF policy, the Firewall Manager administrator can define a set of rule groups to run first in the web ACL and a set of rule groups to run last. Within each set, the administrator prioritizes the rule groups, to determine their relative processing order.
Implementation
final List<FirewallManagerRuleGroup>? postProcessFirewallManagerRuleGroups;
