Events and actions
Scripts are associated with a particular virtual server, and they are event-driven. A script is triggered when the associated virtual server receives an HTTP request or response. Then, it does the programmed action.
|
You can set different script priorities when you run multiple scripts at once. See Prioritize scripts for more information. |
Script events and actions provides the syntax, usage, and examples of the predefined commands that are useful for writing scripts.
