HOw to redirect sessiont timeout page when do AJAX call - ajax

Question

In MVC application, I have made most of the CRUD operations call using AJAX.
Problem is , when session gets timeout then, its unable to redirect to session time out page.
Below is the related code which works fine when there is no AJAX call.
[AttributeUsage(AttributeTargets.Class)] //| AttributeTargets.Method
public class ControllerLogAndAccessFilter : FilterAttribute, IActionFilter
{
public void OnActionExecuting(ActionExecutingContext filterContext)
{
\\check if session is null then redirect to session time out page.
}
}
For login, i just check against the databsae, there is nothing for memebrship provider.
[HttpPost]
public JsonResult Login(string username, string password, bool RememberMe)
{
try
{
UserDTO accDTO = new UserDTO ()
{
UsernAme = username,
Password = DataEncryption.EncryptPassword(password)
};
UserDTO AccDTO = _iAccount.UserAuthentication(accDTO);
if (AccDTO != null)
{
Session["UserId"] = 1;
Session["userdto_Session"] = AccDTO;
// Remember me
HttpCookie myCookie = new HttpCookie("appCookie");
//chkRememberMe.Checked;
if (RememberMe)
{
myCookie.Values.Add("username", username);
myCookie.Values.Add("password", password);
myCookie.Expires = DateTime.Now.AddMinutes(20);
}
else
{
myCookie.Values.Add("username", string.Empty);
myCookie.Values.Add("password", string.Empty);
myCookie.Expires = DateTime.Now.AddMinutes(5);
}
Response.Cookies.Add(myCookie);
// Remember me
return Json(AccDTO.SID, JsonRequestBehavior.AllowGet);
}
else
{
return Json(null);
}
}
catch (Exception ex)
{
}
return null;
}
AJAX Call is made for login and all CRUD operation are using $.AJAX({...});.

Ajax requests should be handled at client side itself, Try this
Attribute:
[AttributeUsage(AttributeTargets.Class)] //| AttributeTargets.Method
public class ControllerLogAndAccessFilter : FilterAttribute, IActionFilter
{
public void OnActionExecuting(ActionExecutingContext filterContext)
{
//TO HANDLE AJAX REQUESTS
if (filterContext.HttpContext.Request.IsAjaxRequest())
{
//If session is null
filterContext.Result = new JsonResult
{
Data = new
{
// put a message which sentto the client
message = "Session Time out"
},
JsonRequestBehavior = JsonRequestBehavior.AllowGet
};
}else{
//
}
}
}
In your javascript
$.ajax(function(){
url:"",
success: function (result) {
if(result.message == "Session Time out"){
//Session timed out handle it
//window.location.href = session timeout url
}
},
});
