The ImpressCMS core exposes some events to make it easier to hook into its functionality and adapt the way things work without having to hack the core itself. One of the easiest ways of using these events is in a preload.
A good example of using events with the preload functionality of ImpressCMS can be found in skenows blog post "How I Added a New Preload to My Site"
