Hi!
I'd like to build small web app (store). One of the to-do things is user
login/logout.
One solution would be with session cookies. Erlang being functional,
continuations come to my mind. Are they possible? Preferred?
How would you do it?
Thanks,
Damir

I doubt things will become simpler if you adopt such a style.
Erlang's paradigm rewards you more if you start a process that awaits
messages from the user: your yaws pages would find this process and
send it messages about what request the user has issued.
An ecommerce store will probably not need that though, having your
yaws pages perform mnesia transactions for the user sounds sufficient.

There is a session server in yaws, yaws.hyber.org has the examples.
In the session's "Opaque" you can store information about the session,
perhaps the user's id, and then keep additional data in a mnesia
table: Such as the user's selected items in the store.
