  10. Complete the following:

      • Action threshold (number of requests): Specify the number of failed requests before the action occurs. Because of the asynchronous request from the browser during page loading, Oracle recommends that you set a threshold of 10 for web applications with basic Ajax usage, and 100 for apps with heavy Ajax usage.

      • Threshold expiry period (seconds): Enter the number of seconds before the threshold expires.

      • Action expire time (seconds):: Enter the number of seconds between challenges to the same IP address. Because of client IP address changes, Oracle recommends that you set the expiry time is set to 120 seconds for apps with mobile users and 3,600 seconds for apps with desktop users only.

      • Interaction threshold (number of interactions): Enter the number of interactions before the threshold expires.

      • Recording period (seconds): Enter the number of seconds to record the user's events.

      • Enable NAT Support box. (optional) Check to enable. When enabled, the user is identified by the IP address and also by a unique hash. This checking prevents blocking visitors with shared IP addresses. Oracle recommends that you disable this NAT support for high-load apps (200+RPS).
