What method do you use to explicitly kill a users session?

In ASP.NET, you can explicitly kill or end a user's session by calling the 'Session.Abandon()' method. This method terminates the current session and removes all the session state data associated with the user.

Here's an example of how to use the 'Session.Abandon()' method:

protected void EndSessionButton_Click(object sender, EventArgs e)
{
    Session.Abandon();
    // Perform any additional cleanup or redirect the user as needed
}

In this example, when the user clicks the "End Session" button, the 'EndSessionButton_Click' event handler is triggered. Within the event handler, the 'Session.Abandon()' method is called to terminate the current session.

After calling 'Session.Abandon()', the session is immediately ended, and all session state data is cleared. The user will be assigned a new session ID when they make subsequent requests to the server.

It's worth noting that 'Session.Abandon()' only affects the current session for the user who triggered the action. It does not terminate sessions for other users or affect their session state.

After calling 'Session.Abandon()', you can perform any additional cleanup or redirection logic as needed for your application, such as redirecting the user to a different page or performing some cleanup tasks before the session ends.

Please keep in mind that ending a user's session should be done with caution and only when necessary. It's important to consider the impact on the user's experience and ensure that any necessary cleanup or data-saving operations are performed before terminating the session.
