What does an 'HTTP Cookie' data structure use to identify a returning user session securely to a server database without prompting continuous password requests?
A.The client computer's current internal hardware operating core temperature
B.A unique Session ID token string stored locally in the browser and transmitted with each HTTP request
C.The user's physical home street address record
D.An unlinked structural HTML layout design code block
Explanation:
When a user logs in, the server generates a unique session identifier and passes it to the browser as a cookie. The browser automatically includes this token with future requests, maintaining the authenticated session.
