------------------------------------
Hi Martin,
yes, thanks. This looks good to me and will solve the problem for sure. I've
appended a very simple repo case below. It's a bit tricky to catch the redirect
response in Firebug, if I can be of any further help, please let me know.
public class AjaxResponseHeadersPage extends WebPage {
public AjaxResponseHeadersPage() {
setOutputMarkupId(true);
add(new AjaxFallbackLink("link1") {
@Override
public void onClick(AjaxRequestTarget target) {
// adding the page to the target will produce a wicket ajax
redirect
// without any cache headers
target.addComponent(getPage());
}
});
add(new AjaxFallbackLink("link2") {
@Override
public void onClick(AjaxRequestTarget target) {
// this produces an ajax response with cache headers set
properly
target.addComponent(this);
}
}.setOutputMarkupId(true));
}
}
and

> Project: Wicket
> Issue Type: Bug
> Components: wicket-core
> Affects Versions: 1.4.17
> Reporter: Timo Weber
> Priority: Minor
>
> Usually HTTP response cache headers are being set in AjaxRequestTarget for
> Ajax responses. But for redirects, the handling is done in WebResponse where
> no cache headers are being set, which could lead to some trouble.
