If you're talking about the disk-based ZEO cache, no.

ZEO supports both persistent and non-persistent (your choice) disk-based
cache, but you have no direct control over cache content or replacement
policy.  You can of course increase the chance of stuff remaining in a
persistent ZEO cache by increasing the cache's size.  To enable a persistent
ZEO client cache, specify the `cache` key in a `<zeoclient>` config section,
or the `cache=` argument to a ClientStorage constructor.
