Hello, I have followed this amazing howto (http://howtoforge.com/high_availability_loadbalanced_apache_cluster) to create my apache cluster. Almost everything seens to be working great (i'm already using unison to sincronyze files ). Then only problem is with php sessions. My users are always losing their sessions because they change servers. How do you solve this? How can i sincro sessions too? Thanks for any kind of help!
