INTEGER, can be read and set, but not unset.

Deprecated. Available inpassmissdeliverlog

The ID of the last WAF rule to be matched by the request.

In the waf_debug_log subroutine, this variable reflects the individual rule that was last processed. Each rule matched by the WAF will set the rule ID variable and invoke the waf_debug_log subroutine, providing an opportunity to log the rule ID.
