onBeginRequest might be the right please. It gets called just before
the URL gets analyzed. But the URL parameters are already available.

Please have a look at the examples. Application.java provides the
hooks. The wiki contains some information about how to do it as well
public final class SignIn2Application extends WicketExampleApplication
{
/**
* @see wicket.protocol.http.WebApplication#getSessionFactory()
*/
public ISessionFactory getSessionFactory()
{
return new ISessionFactory()
{
public Session newSession()
{
return new SignIn2Session(SignIn2Application.this);
}
};
}
And by subclassing WebSession.getRequestCycleFactory() you can create
your own RequestCycles.
