SignOutAsync删除cookie，但在返回到客户端应用程序时重新生成？

// 在登录成功后生成新的Cookie
var claims = new List<Claim>
{
    new Claim(ClaimTypes.Name, "username")
};

var claimsIdentity = new ClaimsIdentity(claims, CookieAuthenticationDefaults.AuthenticationScheme);
var authProperties = new AuthenticationProperties
{
    ExpiresUtc = DateTime.UtcNow.AddMinutes(20),
    IsPersistent = true
};

await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, new ClaimsPrincipal(claimsIdentity), authProperties);

// 注销用户并删除Cookie
await HttpContext.SignOutAsync(CookieAuthenticationDefaults.AuthenticationScheme);

// 在返回到客户端应用程序时重新生成Cookie
await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, new ClaimsPrincipal(claimsIdentity), authProperties);
