Copy Code private const string AntiXsrfTokenKey = "__AntiXsrfToken"; private const string AntiXsrfUserNameKey = "__AntiXsrfUserName"; private string _antiXsrfTokenValue; protected void Page_Init(object sender, EventArgs e) { // The code below helps to protect against XSRF attacks var requestCookie = Request.Cookies[AntiXsrfTokenKey]; Guid requestCookieGuidValue; if (requestCookie != null && Guid.TryParse(requestCookie.Value, out requestCookieGuidValue)) { // Use the Anti-XSRF token from the cookie _antiXsrfTokenValue = requestCookie.Value; Page.ViewStateUserKey = _antiXsrfTokenValue; } else { // Generate a new Anti-XSRF token and save to the cookie _antiXsrfTokenValue = Guid.NewGuid().ToString("N"); Page.ViewStateUserKey = _antiXsrfTokenValue; var responseCookie = new HttpCookie(AntiXsrfTokenKey) { HttpOnly = true, Value = _antiXsrfTokenValue }; if (FormsAuthentication.RequireSSL && Request.IsSecureConnection) { responseCookie.Secure = true; } Response.Cookies.Set(responseCookie); } Page.PreLoad += master_Page_PreLoad; } protected void master_Page_PreLoad(object sender, EventArgs e) { if (!IsPostBack) { // Set Anti-XSRF token ViewState[AntiXsrfTokenKey] = Page.ViewStateUserKey; ViewState[AntiXsrfUserNameKey] = Context.User.Identity.Name ?? String.Empty; } else { // Validate the Anti-XSRF token if ((string)ViewState[AntiXsrfTokenKey] != _antiXsrfTokenValue || (string)ViewState[AntiXsrfUserNameKey] != (Context.User.Identity.Name ?? String.Empty)) { throw new InvalidOperationException("Validation of Anti-XSRF token failed."); } } } it was working properly ,but today when i logged in instead of going to redirected page ,it return following url and move no where,i have cleared up cookies.
