Add the following to your corresponding WebPage...
...
Link logoutLink = new Link("my-link-wicket-id") {
public void onClick() {
getSession().invalidate();
getRequestCycle().setRedirect(true);
setResponsePage(WhereEverYouWantToRedirect.class); [1]
}
};
...
You can also redirect before a page renders:
...
@Override
protected void onBeforeRender() {
super.onBeforeRender();
getRequestCycle().setRedirect(true);
throw new RestartResponseException(WhereEverYouWantToRedirect.class);
}
...
If you need to redirect to an external webpage...
...
Link logoutLink = new Link("my-link-wicket-id") {
public void onClick() {
getSession().invalidate();
getRequestCycle().setRequestTarget(new RedirectRequestTarget("http://www.another-web-site.com") );
}
};
...
[1] it is important to use setResponsePage() variant that takes a page class and not a page instance because a page instance would be stored in session that is now marked for invalidation - thus resulting in a page expired error
