Severity: 2-Critical


iRule execution order might change. For example, you have the following iRules configured on a virtual server: rule1, rule2, rule3, and they all have CLIENT_ACCEPTED. If you do not specify their priority, or if you specify the same priority to each one, when you edit one, the execution order changes. For example, if you edit the rule2 script, the execution order changes to rule2, rule1, rule3.


Execution order changes.


Multiple events have the same priority.


Specify different priorities for iRules containing the same event.

Fix Information

iRule execution order is now maintained after editing the scripts.
