Interrupt a JSF Ajax request

Question

I have a JSF application, in which a RichFaces modal panel is shown using a4j:status while an ajax request is being handled by my backing bean. I want to put a cancel button on the modal panel so a user can interrupt the request.

What is the best way to do this? I'm thinking of something like having the cancel a4j:commandButton call an action on the bean to run FacesContext.getCurrentInstance().renderResponse() but not sure that's wise.

Thanks

一种方法是，在ajax调用过程中，正在执行的托管Bean（即服务器端）中的执行方法必须以一种可以被中止的方式编写，以便它仅返回从而结束请求。这也将保持正确的服务器端状态。
