Under HTTP, it doesn't make any sense: there isn't any "mixed flow" of information going on at all; everything is request-response driven. Given that varnish has as its primary mission to be an HTTP accelerator, and that the behavior is unexpected (in ten+ years of web programming, I've *never* seen this behavior before), I would say that varnish should make the "half-close" either go away (since it provides no benefit) or at least configurable (since it breaks talking to servers which don't expect the HUP).
