The kernel's sendfile() is responsible for a lot of the HTTP server optimization for static resources, and for this case, I think it is true that doing any framing that shows up in the middle of the file would lead to a big inefficiency. I'm not sure how useful this pattern is with dynamic data though. I think people will continue to send most static resources via regular HTTP because it is very, very good at it. jack.
