已经为任何感兴趣的人找到了答案.这是 Katana 中的一个已知错误，即 Katana cookie 管理器和 ASP .NET cookie 管理器发生冲突并覆盖彼此的 cookie.此处的完整详细信息和解决方法:

Have found the answer for anyone interested. It's a known bug in Katana where the Katana cookie manager and the ASP .NET cookie manager *** and overwrite each other's cookies. Full details and workaround here:

下面显示的 SystemWebCookieManager 现在可以在 Microsoft.Owin.Host 中找到.SystemWeb Nuget 包.

The SystemWebCookieManager shown below can now be found in the Microsoft.Owin.Host.SystemWeb Nuget package.

添加 CodePlex 终止时的代码:

Adding the code for when CodePlex dies:

//stick this in public void ConfigureAuth(IAppBuilder app)
  app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                // ...
                CookieManager = new SystemWebCookieManager()
            });

//And create this class elsewhere:
public class SystemWebCookieManager : ICookieManager
    {
        public string GetRequestCookie(IOwinContext context, string key)
        {
            if (context == null)
            {
                throw new ArgumentNullException("context");
            }

            var webContext = context.Get<HttpContextBase>(typeof(HttpContextBase).FullName);
            var cookie = webContext.Request.Cookies[key];
            return cookie == null ? null : cookie.Value;
        }

        public void AppendResponseCookie(IOwinContext context, string key, string value, CookieOptions options)
        {
            if (context == null)
            {
                throw new ArgumentNullException("context");
            }
            if (options == null)
            {
                throw new ArgumentNullException("options");
            }

            var webContext = context.Get<HttpContextBase>(typeof(HttpContextBase).FullName);

            bool domainHasValue = !string.IsNullOrEmpty(options.Domain);
            bool pathHasValue = !string.IsNullOrEmpty(options.Path);
            bool expiresHasValue = options.Expires.HasValue;

            var cookie = new HttpCookie(key, value);
            if (domainHasValue)
            {
                cookie.Domain = options.Domain;
            }
            if (pathHasValue)
            {
                cookie.Path = options.Path;
            }
            if (expiresHasValue)
            {
                cookie.Expires = options.Expires.Value;
            }
            if (options.Secure)
            {
                cookie.Secure = true;
            }
            if (options.HttpOnly)
            {
                cookie.HttpOnly = true;
            }

            webContext.Response.AppendCookie(cookie);
        }

        public void DeleteCookie(IOwinContext context, string key, CookieOptions options)
        {
            if (context == null)
            {
                throw new ArgumentNullException("context");
            }
            if (options == null)
            {
                throw new ArgumentNullException("options");
            }

            AppendResponseCookie(
                context,
                key,
                string.Empty,
                new CookieOptions
                {
                    Path = options.Path,
                    Domain = options.Domain,
                    Expires = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc),
                });
        }
    }
