ONCE CLOSE THE BROWSER SESSION OR CSRF TOKEN REMOVES

 Yes, typically, when the browser session ends (e.g., when the user closes the browser or the session times out), the CSRF token stored in the session will be removed. This is because sessions are temporary storage mechanisms that are tied to a user's browsing session.

Here's how it typically works:

1. Session Lifecycle:

   • When a user logs in or visits a website, a session is created for that user.
   • The session is maintained as long as the user interacts with the website within the session timeout period (configured in the server's session settings).
   • When the user closes the browser, the session is usually terminated, and session data (including CSRF tokens) is cleared.

2. CSRF Token Removal:

   • When you generate a CSRF token and store it in the session, it remains available as long as the session is active.
   • If the session ends (due to browser closure, session timeout, or explicit logout), the CSRF token stored in the session is automatically removed along with other session data.

3. Impact on CSRF Protection:

   • CSRF tokens are effective during the lifetime of a session because they help prevent CSRF attacks within that session.
   • When the session ends, the CSRF token becomes invalid, and any subsequent requests made by the user would require a new CSRF token (which would be generated when a new session is established).

It's essential to consider the session timeout settings in your application's configuration to ensure that sessions are appropriately managed and tokens are invalidated when sessions end. Additionally, implementing mechanisms like token regeneration on each request can further enhance the security of your CSRF protection.
