for the serious minded tech's in here. In my infrastructure, I have a cisco 11000 series load balancer with a content rule that points to a keepalive file on two servers. One server shows alive giving a 200 response to the CSS while the other server reports back with a 304 code. the 304 code is "Not Modified / The cached version of the requested file is the same as the file to be sent." anyone got an idea?
