Thanks for the pointer. I have no C++ experience so far, this might be an
opportunity to learn some (at some stage ;-).

Some notes on ESI (based on playing with it for an hour): if you have
trouble to get your ESI-enabled content cached, make shure your
Surrogate-Control header looks like this:

Surrogate-Control: max-age=60+60, content="ESI/1.0"

The '60+60' looks strange, but it's not at all (see
http://www.esi.org/architecture_spec_1-0.html#s2-2-3). Performance drops a
bit with ESI: about 600/s without ESI vs. 130/s with four unconditional
includes on my small laptop. Note that the ESI number is without
compression, 600/s would be hard to reach without.
