Comment (by dcf):
A back-of-the-envelope calculation of potential savings: In
[https://lists.torproject.org/pipermail/tor-dev/2014-December/007916.html
November 2014] we had 167 M requests and 1269 GB on meek-amazon. If we
saved 413 − 162 = 251 bytes on each request, that's 167 M × 251 B = 39 GB,
or 3% of total bandwidth, or somewhere between $4.50 and $7.50 in cost,
depending on the region. These numbers are approximate because TLS pads
application data records so we don't save exactly 251 bytes on each
request, and additionally the Host and Content-Length headers can change
the length of the header.
