integer As uint32 As uint32
max_execution_time
Optional

The maximum period of time WAF processing is allowed to take for a single request. A value of 0 (zero) means no limit and should not be chosen in production deployments. It is only used for exceptional situations where crashes of se_dp processes are acceptable.

In WAF policy mode 'Detection', the request is allowed and flagged for both failure mode 'Closed' and 'Open'. In enforcement node, 'Closed' means the request is rejected, 'Open' means the request is allowed and flagged. Irrespective of these settings, no subsequent WAF rules of this or other phases will be executed once the maximum execution time has been exceeded. Allowed values are 0-5000.
