1
Creates a hybrid CacheManager.
2
Creates a pool of size 4 MB from primary-server-resource, with a dataPercent value of 25.
3
Creates a pool of size 12 MB from primary-server-resource, with a dataPercent value of 50.
4
Creates a Cache using pool1 created from Step 2 above.
5
Creates a Cache using pool2 created from Step 3 above.
