Session Cookie
In plain terms
A temporary cookie that expires when the browser closes.
Going deeper
A session cookie stores session data only for the browsing session, deleted when the browser closes, often holding a session ID. It's short-lived by design.
Under the hood
Lacks a persistent expiry; commonly references server-side session state for login.
Examples
Login sessions, shopping carts, temporary state, session IDs.
Think of it like...
Like a day pass that's discarded when you leave the venue.
