abstract:In computer science, a session identifier, session ID or session token is a piece of data that is used in network communications (often over HTTP) to identify a session, a series of related message exchanges. Session identifiers become necessary in cases where the communications infrastructure uses a stateless protocol such as HTTP.
"Digital certificates are required for connection to the RRP service, but user ID and passwords are required to initiate a session, " explains Rick Wesson, an IETF member and a senior software engineer at Alice's Registry Tools.
