networking 1. A lasting connection between a user (or user
agent) and a peer, typically a server, usually involving
the exchange of many packets between the user's computer and
the server. A session is typically implemented as a layer in
a network protocol (e.g. telnet, FTP).
In the case of protocols where there is no concept of a
session layer (e.g. UDP) or where sessions at the sessionlayer are generally very short-lived (e.g. HTTP), virtual
sessions are implemented by having each exchange between the
user and the remote host include some form of cookie which
stores state (e.g. a unique session ID, information about the
user's preferences or authorisation level, etc.).
