As someone who's had a lot of headaches with
ManagedEntityIdentityInterceptor...let me just say "Yay!"

AFAIK there is no standard way to do this.  I have a way to detect it
for Jboss/Tomcat (by checking for the presence of the ClusterManager
MBean, but that probably won't help unless we want to create a
pluggable component which has tweaks/advice for the each app server,
in which case each could also have an implementation of things like
"isSessionClustered(HttpSession)."  That's a potential maintenance
nightmare, but if someone from each large app server maintained their
tweaks component, it could work.
