storing cache

[Fabien JALABERT]

Hello (again)
I load data in the cach that need lots of calculation. I would like to 
be able to store this cache in a file, then is the server stops or 
crash, I would like to load the store cache file, and then to update 
value at time with low load on server.

I've found a parameter in cache.properties:

cache.file.store=data/utilcache


Is this the correct parameter ? What is this parameter ? Should I use 
another one ?

Thanks a lot.
