Explain the fundamental problem that session management aims to solve in the context of the HTTP protocol.
Which of the following HTTP status codes is typically returned by the server after a successful user login and session creation, indicating that the client should load a new page?
Describe the key steps a server takes to create a new session after successfully validating a user's login credentials. Include how a unique session ID is generated and where session data might be stored.
Which Set-Cookie
attribute prevents client-side scripts (like JavaScript) from accessing the cookie, thereby mitigating certain XSS attacks?
When setting a session cookie, which two Set-Cookie
attributes are primarily used to define its lifespan?
After a browser receives a Set-Cookie
header containing a session cookie, what are its responsibilities regarding this cookie for subsequent requests to the same domain?
When a browser sends a session cookie with a subsequent request, the cookie is included in the (7) HTTP header.
Explain how the server uses the session cookie received from the browser to identify the user and potentially authorize access to protected resources.
Distinguish between 'idle timeout' and 'absolute timeout' in session management, and briefly describe how an explicit 'logout' action terminates a session.
Which security vulnerability is primarily mitigated by setting the SameSite=Lax
or SameSite=Strict
attribute on a session cookie?
Beyond HttpOnly
, Secure
, and SameSite
attributes, name two other best practices for securing cookie-based sessions.
Describe the entire end-to-end flow of cookie-based session management for a traditional server-rendered web application, from a user logging in to successfully accessing a protected resource. Detail the interactions between the client (browser) and the server at each significant stage, including relevant HTTP headers and server-side actions.
