如何检查会话是否超时？

Question

我们有20个微服务都在使用客户端库。

这个库只是为微服务提供了一种连接到目的地的方法：CRM Dynamics。

在每个服务中，我们都有一个调用此库的包装器：

public static class Client
{
    public static HttpClient Instance;
    static Client()
    {
        Instance = new TheCrmClient<AdfsAuthenticationHelper>(MyConfigSettings).HttpClient;

    }
}

在每项服务中，我们都像这样使用客户端：

        //Issue request
        var response = Client.Instance.SendAsync(request).Result;

ADFS会话超时后，我们将收到401响应。

我们如何在收到401响应时强制重新验证？

认证发生在GetHttpsClient（）中：

public class TheCrmClient<T> where T : IAdfsAuthenticator
{
    private readonly RestCRMClientConfiguration _configuration;
    private IAdfsAuthenticator _authenticator;
    private HttpClient _https;

    public TheCrmClient(RestCRMClientConfiguration configuration)
    {
        _configuration = configuration;
    }

    public HttpClient HttpClient => GetClientHttps();

    private void InitializeAuthenticator(HttpClient client)
    {
        _authenticator = Activator.CreateInstance(typeof(T), client) as IAdfsAuthenticator;
    }

    private HttpClient GetClientHttps()
    {
        var clientHandler = new HttpClientHandler
        {
            UseCookies = true,
            CookieContainer = new CookieContainer(),
            AllowAutoRedirect = false
        };

        _https = new HttpClient(clientHandler)
        {
            BaseAddress = _configuration.GetServiceUri(RestCRMClientConfiguration.UrlProtocolType.Https)
        };

        if (_authenticator == null)
            InitializeAuthenticator(_https);


        _authenticator.Authenticate(_configuration.GetNetworkCredential(),
            _configuration.GetAuthenticationTestEndpointUrl(RestCRMClientConfiguration.UrlProtocolType.Https));

        return _https;
    }
}

澄清请求的生命周期是：
