Re: FYI: Tools to evaluate header compression algorithms

[Roberto Peon <[e-mail]>]

As Mark already points out, this is pretty different as it only includes
the first page. Given how the compressors in general work, this is likely
to bias the results towards compressors that do better on only that page
load to the detriment of those which do better on further page loads.

We need traces of the "average user interaction" for each site to do a
really good job.
