close session in mvc 4

Navigation
1

I can not close an open session.

I use this method but it DOES NOT WORK. 

<a>
href="@Url.Action("CerrarSesion","Home")"> <i class="icon-key"></i> Cerrar Sesión
</a>

Here I have the driver. 

<HttpPost()>
    Function CerrarSesion() As ActionResult 
        If IsNothing(Session) = False Then 
            Session("usuario") = Nothing 
            Session("usu") = Nothing 
            Session.Clear() 
            Session.Abandon() 
        End If 
        FormsAuthentication.SignOut() 
        Return RedirectToAction("Index", "Home") 
    End Function

When he uses this form he tells me that he "can not find the resource".

and here I have this function and use it on a button and it does not work ... 

<script type = "text/javascript">
    function SessionAbandon() {
        $.ajax({ 
            type: "POST", 
            url: "/Home/CerrarSesion", 
            data: {}, 
            contentType: "application/json; charset=utf-8", 
            dataType: "json", 
            async: true, 
            error: function (XMLHttpRequest, textStatus, errorThrown) { 
                alert(textStatus + ": " + XMLHttpRequest.responseText); 
            } 
            }); 
    } 
</script>

For @Url.Action to work, what you have to do is remove <HttpPost()> from the controller.

@Url.Action is not designed to post and you do not need to post it either.

The instruction FormsAuthentication.SignOut() is enough to loosen up, that can be validated with the variable context.User.Identity.IsAuthenticated . The only thing that I find strange there is that the ajax can not redirect you with a Return RedirectToAction("Index", "Home") you would have to return a HttpStatusCodeResult(401); // Unauthorized or simply assign it in the response Response.StatusCode = 401; and catch it in the success of the ajax or configure it in the ajax setup: 

$.ajaxSetup({
    statusCode: {
    // unauthorized
    '401': function () {
      window.location.href = action.home.index;
    }
});
