IDP node stickiness without an SLB?

We also have a load balancer that doesn't know sticky.  We use
Apache and mod_proxy to create artificial stickyness.  A short
lived cookie identifies the host where a user first arrives.  If a
subsequent request lands on the wrong host it is proxied to the
right one.  If this might work for you lookup idpproxyclustering
on the shib wiki.
