Most of my stuff is in the cloud, so I use their load balancing services.

HAProxy does have sticky sessions, which you can enable based on IP so 
it works with other protocols: 2 Ways to Enable Sticky Sessions in 
HAProxy (Guide)

Magnus,

That is a feature of the load balancer. Most of them have that

HAProxy, for on-prem things.  In the cloud I just use their load balancers 
rather than implement my own.
