I have to setup a load balancing system. At the moment I have two machines running Nginx 0.8.52, PHP-FPM (on unix socket) and an application based on PHP Symfony 1.4.11.
On a third machine, I have to choose a which balancer to install.
I've already used Varnish for static file caching, but I don't know if Varnish load balancing can handle Symfony PHP sessions. Another option would be Nginx load balancing with ip_hash.
Which one is the best?
Thanks in advance
