IDP HA -- Why?

[Sam Agnew]

Simple (possibly stupid) question here.

If I have a user who has authenticated and now have a valid session my understanding is that they are good with the SP until cookie expires.

If my IDP fails over to another IDP that doesn't know anything about the sessions my user is still good. Where is the benefit in fiddling with Teracotta/memcached to get session retention during failover?

Thanks!

Sam
