Technical Note: How to increase cache rate on a FortiCache cluster
Description
Scope
Solution
On a FortiCache cluster, requests for the same URL may have hit each cache device and been cached separately on each. FortiCache 4.2 introduces the Cache Collaboration feature, where the storage of all devices within the FortiCache HA Cluster is accessible as a shared entity. This allows content cached by one device to be shared by other FortiCache devices within the cluster, significantly increasing the cache rate.
Scope
FortiCache OS 4.2 and above.
Solution
config wanopt cache-service
set prefer-senario balance
set collaboration enable
set acceptable-connections any
end
