Tenho o seguinte script:

function OpenIdLogon(e) {
        $.post("/Account/OpenIdLogOn/", { token: e }, function (data) {
            $("#userNavigation").html(data);
            $(".auth_box").hide();
            $(".kb_fading").hide();
        });
    }

Esta é a ação:

public ActionResult OpenIdLogOn(string token)
        {
            WebClient cli = new WebClient();
            string json = cli.DownloadString(new Uri("http://ulogin.ru/token.php?token=" + Request.Params["token"] + "&host=" + Request.Url.Host));
            var obj = JObject.Parse(json);
            if (obj["error"] == null)
            {
                var userName = obj["nickname"].Value<string>();
                var email = obj["email"].Value<string>();
                FormsAuthentication.SetAuthCookie(userName, true);                    
            }

            return PartialView("UserNavigation");
        }

E, minha UserNavigation:

@if (Request.IsAuthenticated)
{
    <a href="#" class="username"><span>@Context.User.Identity.Name</span><i class="icon iUser"></i></a>
    <ul class="headLine_link">
        <li><a href="#">Profile</a></li>
        <li>
            @Html.ActionLink("Logg Off", "LogOff", "Account", null, new { @class = "exit" })</li>
    </ul>

}
else
{    
    <ul class="headLine_link">
        <li><a id="regLink">Register</a></li>
        <li><a id="authLink">Log On</a></li>
    </ul>
}

O problema em queRequest.IsAuthenticated igual a true somente após a página de atualizaçã
