This package provides two Snap extensions, implementing
sessions as either memory-backed arbitrary types, or as
client-side cookie-backed serializable types. The latter
clientsession package to encrypt the cookie for
security. In both extensions, sessions are protected from
session stealing by checking the source IP address, and
have a configurable timeout (optional for the cookie-
backed back end). The session type is user-defined.
In addition, a library is provided for a continuation- based programming model called dialogues, which allows natural specification of stateful interactions with the client that span multiple requests. Because the session type is not serializable, this requires the memory-backed implementation.
