In 1.4.x I override WebRequestCycle and did the redirected in onBeginRequest
method so for 1.5 overriding the AbstractRequestCycleListener's
onBeginRequest seems like the best choice. I can't override the
applicaiton's createRequestCycle method since it has been made final.
Changing the web request cycle was done to ensure that the user could not
perform any further actions till they agreed to the terms and conditions of
the website. Is their a better way to Wicket way to do this? At this point
all i can think of doing is adding redirects to each page.
I've also tried overriding newWebRequest and newWebResponse but get the
following exception when I query the web session from these methods.
java.lang.IllegalArgumentException: Argument 'requestCycle' may not be
null.
