Session (computer science) In computer science and networking in particular, a session is a time-delimited two-way link, a practical (relatively high) layer in the TCP/IP protocol enabling interactive expression and information exchange between two or more communication devices or ends – be they computers, automated systems, or live active ...
PHP is a general-purpose scripting language that is especially suited to server-side web development, in which case PHP generally runs on a web server. Any PHP code in a requested file is executed by the PHP runtime, usually to create dynamic web page content or dynamic images used on websites or elsewhere. [282]
Session ID.

Session identifiers become necessary in cases where the communications infrastructure uses a stateless protocol such as HTTP.
Microneedling is a cosmetic procedure that’s primarily used to minimize the signs of aging. During a standard session, a dermatologist uses a special roller or device with needles to prick the ...
PHP generally follows C syntax, with exceptions and enhancements for its main use in web development, which makes heavy use of string manipulation. PHP variables must be prefixed by " $ ". This allows PHP to perform string interpolation in double quoted strings, where backslash is supported as an escape character.
A session key is a single-use symmetric key used for encrypting all messages in one communication session. A closely related term is content encryption key ( CEK ), traffic encryption key ( TEK ), or multicast key which refers to any key used for encrypting messages, contrary to other uses like encrypting other keys ( key encryption key ( KEK ...
Session hijacking. In computer science, session hijacking, sometimes also known as cookie hijacking, is the exploitation of a valid computer session —sometimes also called a session key —to gain unauthorized access to information or services in a computer system. In particular, it is used to refer to the theft of a magic cookie used to ...
Session started as a fork of another messenger, Signal, aiming to build upon its foundation. However, concerns about the centralized structure of Signal Protocol and potential metadata collection led the team to deviate and create their own protocol, called "Session Protocol". This approach prioritized increased anonymity and decentralization.
