How can I override the render strategy for a specific page in wicket

Question

I have an application which needs to accept a POST request from an outside server, to confirm payment. I don't want to break the default wicket render strategy (REDIRECT_TO_BUFFER) which is serving to give the users a nicer experience than ONE_PASS_RENDER would, however, the external service is not happy with the 302, and keeps retrying until it gives up.

Is there some sensible way that I can tell wicket to use ONE_PASS_RENDER for only the specific page that handles this request?

Answer 1

Try using a Resource instead of a Page to handle this request. That way, you can return whatever response you want (both HTTP headers and payload) to keep the external service happy.

It's a lower level API, though. If you need to respond with a rendered page, you may need to render it yourself (with lots of println() calls), or hack some way to Wicket to do it.

But since it is a response to a external service, I assume it will expect some kind of simple text, XML or JSON response, which are easy enough to do by hand.
