[erlang-questions] Stateful gen_servers
Sun Oct 7 06:23:56 CEST 2007
Thanks David for the tip. I think I can use session-id to track state and have the client pass it with each request. Though, I would liked it if somehow that session-id is implicitly passed. Also, it would help if you can share a sample application.

You could have each client do something like:
Then in the server, the State field could have a dict of Sessions
(generated via make_ref()?) to state information
If that's not enough, I have a tictactoe server that I wrote recently
that maintains the states of games this way, so let me know if you
want some live code that does this
