Short version: No. Longer version: It's not currently possible and probably hard (but not impossible) to do. But I think (but this is pure speculation) that a Lift session is rather heavy since it contains closures for all the callbacks that have been active within the last 10(?) minutes, the overhead of serializing the session state for each request (which you need for HA) would be substantial. > I've looked around, but I have not found any good articles about how > to scale Lift horizontally. Probably because it has not been done (without sticky sessions) /Jeppe -- You received this message because you are subscribed to the Google Groups "Lift" group.
