This text file allows you to create event handlers for a wide variety of events exposed by both the application as a whole and by individual sessions. You can also include methods and server-side include files that will apply globally to the entire application.

Configuration settings can apply to every application on the web server, to specific applications, or to specific subdirectories within an application.
