I am having a problem with caching.
the setup I have is multiple WordPress installs with a load balancer in front. I am syncing the data. WP Super Cache is enabled, but we are occasionally getting cached files sent so that data served from http://www.domain.com and data served from domain.com are different. On the backend, in the cache folder, I have a directory for http://www.domain.com and also domain.com, and these seem to get out of sync over time.
Any ideas on how I can resolve this?
