[rules-users] Stateless or stateful knowledge session in drools server

Hello all, I am new to drools. My company is looking into switching from a commercial rule engine to drools. Our existing codebase is .net not Java. We are trying to integrate drools into our existing .net application by calling into a drools-server using it’s restful interface. Our current rule engine only works in a stateless mode so I am trying to figure out how to get drools-server to work in a stateless mode. I have posted before that I have been having difficulty using a stateless session with ruleflows ( http://drools.46999.n3.nabble.com/Ruleflow-not-working-with-stateless-ses...). I have noticed that the stateful sessions seem to work fine as far as ruleflows are concerned. I am wondering if I can use a stateful session instead of stateless. Our application could have 100s of unique users per minute. The rule engine provides a unique decision for each user based on their specific data. So, each user’s data / facts should be isolated. There can’t be any data sharing between users, that would make the rule engine decisions invalid. How would I configure a stateful session to work in this scenario? Is it possible? Thanks, Tim S.
