Session cookies are cookies that last for a session. A session starts when you launch a website or web app and ends when you leave the website or close your browser window. Session cookies contain information that is stored in a temporary memory location which is deleted after the session ends. Unlike other cookies, session cookies are never stored on your device. Therefore, they are also known as transient cookies, non-persistent cookies, or temporary cookies.

A CSRF token is a unique, secret, unpredictable value that is generated by the server-side application and transmitted to the client in such a way that it is included in a subsequent HTTP request made by the client. When the later request is made, the server-side application validates that the request includes the expected token and rejects the request if the token is missing or invalid. CSRF tokens can prevent CSRF attacks by making it impossible for an attacker to construct a fully valid HTTP request suitable for feeding to a victim user. Since the attacker cannot determine or predict the value of a users CSRF token, they cannot construct a request with all the parameters that are necessary for the application to honor the request.
