Rest API - REST API Fundamentals

AStore user sessions on the server and use session IDs in cookies

BKeep user login state in server memory between requests

CUse JSON Web Tokens (JWT) sent with each request for authentication

DRequire clients to log in once and rely on server session

Step-by-Step Solution

Solution:

Step 1: Identify stateless authentication methods
JWTs carry all auth info in each request, no server session needed.
Step 2: Compare with session-based methods
Session-based methods like storing sessions on the server or keeping login state break statelessness.
Final Answer:
Use JSON Web Tokens (JWT) sent with each request for authentication -> Option C
Quick Check:
JWT enables stateless authentication [OK]

Quick Trick: JWTs keep REST APIs stateless with auth [OK]
