Just to sanity check I navigated to www.google.com -- the page load made 11
requests, each with the same 8 identical cookies. Thus the reference set in
this example saves 8 bytes per frame (as opposed to the 1.57 bytes in your
analysis).

I'd suggest trying to capture data on a single domain to show the affect
the compression has on repeated cookies.
