Method summary

The following table briefly describes the application event methods that you can implement in Application.CFC:

Method name	Method runs when
`onApplicationEnd`	The application ends: the application times out, or the server is stopped
`onApplicationStart`	The application first starts: the first request for a page is processed or the first CFC method is invoked by an event gateway instance, or a web services or Macromedia Flash Remoting CFC.
`onError`	An exception occurs that is not caught by a try/catch block.
`onRequest`	The `onRequestStart` method finishes. (This method can filter request contents.)
`onRequestEnd`	All pages in the request have been processed:
`onRequestStart`	A request starts
`onSessionEnd`	A session ends
`onSessionStart`	A session starts

All parameters to these methods are positional. You can use any names for these parameters.

When a request executes, ColdFusion MX runs the CFC methods in the following order:

The onApplicationEnd, onSessionEnd, and onError CFCs are triggered by specific events.
