reload the command cache automatically

[Bhargav N Balasubrahmanya]

Hi, i'm using wps 6.0.1 and trying to use the command cache in my application. But the requirement is that the cache should be reloaded automatically after some specified time, what currently happens with commandcache is that it gets reloaded only if it gets a request and the cache has been invalidated.
The problem is that the reloading of cache only after there is a request causes considerable delay for the first time for the first user. so, i would want the cache to reload automatically after some specifiede time, no matter if there's a request or not.
Thanks.
