You have either to store your sessions on a common shared
backend (moderns web scripting languages allows storing
sessions in memcached or database, but you can also use NFS
for instance, ..), or just reduce the odd to loose the
sessions (for instance by using the ip_hash option for the
upstream backend, so clients will stick to the same server
unless nginx detects this servers isn't available anymore).
