ColdFusion can execute code when an application starts and ends, when a session starts and ends, when a request starts and ends, and more. But what if you need to execute code when a server starts up? Granted, this is not a common use case, but when needed, we've had to use onApplicationStart for this, probably doing something like:
ColdFusion Centaur adds the ability to define code to be executed onServerStart.
By default this is a method named onServerStart in server.cfc. But, actually, it can be in any ColdFusion Component, including an Application.cfc. In ColdFusion Administrator you can point to the CFC and method to be invoked, and ColdFusion will execute the code on server start-up before processing any requests.
