1. Re: Eviction and cache store
davepleydell Oct 8, 2009 8:26 PM (in response to davepleydell)Here is my xml file:

I was trying to do a test where I check the size of the cache after reading a value, pause for a bit to allow the item to be evicted and recheck the size of the cache. At the moment that isn't doing as I thought it might. -

Expiration will remove items from the cache and cachestore.

Eviction will only remove items from memory but will leave the item in the cachestore? Is that correct?

How do we set the time the item remains in memory before being removed? (but still in the cachestore).
Eviction is not time based, but rather it is size based. You would set up a max number of entries and once this is reached entries get evicted from memory.
