Sometimes buffering a response is less than ideal. It would be nice if we could send the head tag along with any css or script includes to the browser as quickly as possible. Then the browser can download external resources while we're still processing data on the server. If this were possible, total response time may remain the same, but the time to first byte would be decreased and the page would load faster as external resource can be downloaded in parallel.
