yes, that's right. only it's not really a dummy page.
it's a redirect page whose function is to locate the
right server.
public class ServerLocatorPage extends WebPage { ... // what you said }
btw, you can do anything in Wicket you can do in a servlet
because you can always drill down to the HttpServlet classes:
getWebRequestCycle().getWebRequest().getHttpServletRequest()
getWebRequestCycle().getWebRequest().getHttpServletRequest().getSession()
getWebRequestCycle().getWebResponse().getHttpServletResponse()
