如何处理MVC 3中的会话超时

var sessionTimeout = 20 * 60 * 1000; // 20 minutes
var timeoutWarning = 18 * 60 * 1000; // 18 minutes

var sessionTimer;

function resetSessionTimer() {
    clearTimeout(sessionTimer);
    sessionTimer = setTimeout(logout, sessionTimeout);
}

function showTimeoutWarning() {
    // Show a warning message to the user
    alert("Your session will expire in 2 minutes. Please continue your activity to keep the session active.");
}

function logout() {
    // Perform logout action
    // Redirect the user to the login page or display a logout message
}

// Start the session timer
resetSessionTimer();

// Bind events to reset the session timer on user activity
$(document).on("mousemove keydown", function() {
    resetSessionTimer();
});

// Show the timeout warning when the session is about to expire
setTimeout(showTimeoutWarning, timeoutWarning);

protected void Session_Start()
{
    // Set session timeout to 30 minutes
    Session.Timeout = 30;
}

  <system.web>
    <sessionState timeout="30"></sessionState>
