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)).
