Make HTTP messages carry state
Created by server and stored in browser
If no domain is explicitly specified for a cookie, it defaults to the domain of the server that sent it. Cookies are vulnerable to attacks and pose a risk of information theft, so they should be used only when their speed or convenience is necessary.
The term comes from “magic cookie,” which refers to a packet of data that a program receives and returns unchanged. Cookie attributes store information such as expiration, domain, and flags like Secure and HttpOnly. In MSA, cookies are convenient when moving across different subdomains.
