In a previous mail Mario wrote (about sessions): "You are not obliged to use Durus. Any other persistence mechanism will do, as long as you satisfy the API as defined in the class qp.pub.publisher.DurusPublisher." I was wondering if anyone had already done the work and plugged QP into MySQL or even better PostgresSQL? I have nothing against Durus, in fact like it, but my hosting provider already provides MySQL and Postgres instances for me to use and will charge extra for using Durus because it will count as another chargeable "long running process" along with QP itself. An increase in cost I'd like to avoid. Regards, Tristan
