I want to check requests before my web pages are rendered.


In Wicket 1.4.x, you have to extend [Web]RequestCycle, so that you an override the hook methods (onBeginRequest(), onEndRequest(), onAfterTargetsDetached(), etc.), and override Application.newRequestCycle() to return the custom class.

In Wicket 1.5.x, this mechanism has been refactored, so you can just implement the RequestCycleListener, which provides the same hooks. This new mechanism is much better, since you can compose and reuse listeners.


In Wicket 1.4.x (don't know if this has been kept in 1.5) you have RequestCycle#onBeginRequest() and RequestCycle#onEndRequest() that you can override.
