But it's not about a marginal speed up here, it's about a server not being certain whether it wants its data to be cached or not until they're complete (think about data being assembled from multiple web service requests), and preferring to first ask that this response is *not* cached as-is until it can confirm it was entirely successful with a trailer. I think this totally makes sense. Willy
