Session identifiers become necessary in cases where the communications infrastructure uses a stateless protocol such as HTTP.
v. t. e. HTTP header fields are a list of strings sent and received by both the client program and server on every HTTP request and response. These headers are usually invisible to the end-user and are only processed or logged by the server and client applications.

Session fixation. In computer network security, session fixation attacks attempt to exploit the vulnerability of a system that allows one person to fixate (find or set) another person's session identifier. Most session fixation attacks are web based, and most rely on session identifiers being accepted from URLs (query string) or POST data.

The Session Description Protocol (SDP) is a format for describing multimedia communication sessions for the purposes of announcement and invitation. [1] Its predominant use is in support of streaming media applications, such as voice over IP (VoIP) and video conferencing. SDP does not deliver any media streams itself but is used between ...
