Torstein -

We have a client who is interested in ESI and also requires gzip (as I
think most would), and we've been working on it on the back burner for a
while. Faster work from us depends on the client's priorities. It's not
a trivial undertaking, but I have at least got to the point of
understanding the ESI request flow enough to guess where the encoding
should probably be performed.
