Hi,

A hint for debugging: the request to login?0 should be handled by
org.apache.wicket.core.request.mapper.BufferedResponseMapper not by
WebPageRenderer. Check why there is no stored response.

A suggestion: try to make your login page stateless. Otherwise every
hit to your application will create a new http session. I.e. an
attacker can cause a denial of service.
