The SOSP'99 paper by Wolman et al showed similar things (I don't know if
that was related the presentation you pointed to). Their traces were
collected in UW and Microsoft in may 1999. They did not show cookies, but
they did show that about 60% requests in UW trace went to cacheable pages,
and 51% in the MS trace.
