Memcached (11) Memcached-session-manager

Introduced

Memcached-session-manager is the session in Tomcat, hosted into the Memcache management, to achieve the stateless application of Tomcat.

But in the author's experience, we generally do not use this technique when developing. Instead, you use the session in an existing project and quickly upgrade to a stateless application using this approach.
