Sure, but there may be latencies or so between nodes which may bring problems, and it is always hard to troubleshoot this kind of problems. Sticky session generally lowers probability of this kind of operational problems, this is why I like them and use them ;-) But correctly configured replication is necessary even in case of sticky sessions to have failover. That's why we use sync, not async. But, I agree sticky sessions would be nice. > We also don't support sticky sessions at the moment as there's no > cookie to stick on. We're going to look into supporting sticky > sessions soon. Some loadbalancers are able to make sticky session on his owns, even if application itself do not provide any cookie. We use this on RHD website, we have F5 loadbalancer which handles sticky sessions for us (I think it creates his own cookie), and is able correctly failover when keycloak node dies. What makes it non-trivial is that there are two different things using the same session and user. The users browser (for login redirects and also html5 apps) and also server-side applications. These will have different IP addresses. So simply setting up sticky sessions based on the source won't work. So don't tell your users that Keycloak doesn't support sticky sessions at all, it works with sticky sessions correctly if provided by loadbalancer by some way not relying on cookie provided by Keycloak itself. ;-) Vlastimil > > On 26 February 2016 at 09:29, Vlastimil Elias <velias(a)redhat.com > <mailto:velias@redhat.com>> wrote: > > What about configuring Loadbalancer to use sticky
