Client side sessions

Question

I want the clients of several related web apps to hold their own authentication state. This improves scalability, because no session replication between cluster nodes is nee

Answer 1

You can avoid duplication of data in a clustered environment by using a state server - a server that is well known by all the nodes in the clusters and maintains the session data for all the users. Every time a user performs a request, it send a cookie with session id to the applications server; this one should retrieve the session from the state server. This is possible for asp.net development, but I'm not sure how easy Java supports this approach.
