[OFBiz] Dev - load balancing with entity engine cache

[Mark Gordon]

Excellent!  That is what I was looking for!!

I am using 3.0 of the entity engine and I have made a few minor changes 
to deal with my odd database situation.  I may have to upgrade to the 
latest version and add my changes.

Thanks!
