So just to confirm... does that mean that this paragraph:



There is a further consideration for active/active deployments: session 
affinity. Session affinity is a feature of most load balancer equipment 
where the device performs state management for incoming requests and routes 
a client to the same node for subsequent requests for a period of time. This 
feature is recommended and required to avoid servlet container session 
replication, which is generally more complex and less reliable. The core of 
this requirement is that servlet container session storage is used to 
maintain state for the CAS login and logout Webflows. While it is possible 
to achieve truly stateless active/active deployments by plugging in 
client-based state management components, such configurations at present 
have not been proven and are not recommended without careful planning and 
testing.



from 
https://apereo.github.io/cas/development/planning/High-Availability-Guide.html 
is no longer applicable and should be removed (or turned into a paragraph 
that explicitly states you don't need session affinity any more)?



Yes, the paragraph should definitely be changed. Note that you can still 
configure CAS to use server-backed sessions, and certain features of CAS do 
require that behavior anyway.
