The Flex cache organizes the cached objects efficiently by using a "last-recently-used" policy. This page writes a large filler text to generate cacheable entries. If the byte size of all cached entries is raised up to the maximum byte size for all cached entries, the flex cache finalizes the last recently used entries to resize the cache down to the average byte size for all cached entries:

Cached keys: 0
Cached variations: 0
Maximum size of all variations: 8000000 bytes
Average size of all variations: 6000000 bytes
Current size of all variations: 0 bytes

Warning!

The FlexCache is currently not enabled!
For the examples to work correctly, you have to enable the FlexCache as described on the page Configuration options in this documentation.

Please refer to the Flex Cache Administration for further details about the cached keys and entries.
