The redirect pattern makes sense for a POST request that creates a resource, where you can then redirect to the newly created resource.

QUERY on the other hand makes sense for cases where the request doesn't cause any state changes on the server, and there is no resource to redirect to.

That is the good old fashion workaround. But why is it better than a form causing an HTTP QUERY.

If we can do QUERY forms, it would be an ideal time to add JSON encoding for forms.
