Here, we use 2 keepalived/lvs servers in direct routing for HA, then
n cache servers with nginx (for consistent hashing + some
basic http/php) and, behind, varnish (or squid, not decided yet... varnish
memory/disk handling seems "cleaner" and a little bit faster, but on the
other hand squid cache will survive a restart (maybe varnish new
version 3.x implemented it, not sure)).
