session
<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 session layer 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.).
See also login.
2. A lasting connection using the session layer of a networking protocol.
