I measured the headers in ajtaylor's above post. Zappos delivers different headers each time, and currently they're only giving me 599 bytes, including zero Link headers. I agree of course that you can't consider all of it a waste. My point was just that their HTTP overhead is exceptionally large, and their superfluous headers adversely affect all of their users despite the fact that almost none of their users will ever read them. The fact that their X-Core-Value in ajtaylor's example was "8. Do More With Less" makes them seem clueless about the real impact of HTTP overhead.
