# Mel,

#   Sorry, I read too much of a previous problem I had into your question and
# probably spun you off in the wrong direction.  Jim's comment points you in
# the right direction, but its only going to get you so far because of a
# limitation in combining polymorphism and HasManyThrough.  You will run into
# this error trying to do what you want to do:

Sessions and Conversations

HTTP is a stateless protocol. Sessions allow us to chain multiple requests together into a conversation between client and server.

Sessions should be an option of last resort. If there's no where else that the data can possibly go to achieve the desired functionality, only then should it be stored in the session. Sessions can be vulnerable to security threats from third parties, malicious users, and can cause scaling problems.

That doesn't mean we can't use sessions, but we should only use them where necessary.
