How to check "Session" from the .html page in `.NET`

Question

Basically I am trying to check the Session value from the .html page. SO what far I done that is

In ASPX I am storing the value in session and redirect into an html page.

Session["user_id_no"] = "1234";
Response.Redirect(url);

From HTML I am calling an REST GET method.

var check= $.ajax({
    url: "/loginCheck",
    type: 'GET',
    success: function (result) {
        return result;
    },
    async:false
});

REST API and Method implementation

[HttpGet]
[Route("loginCheck")]
public bool checkLoginStatus()
{
    SessionClass sc = new SessionClass();
    bool user_id_check = sc.check("user_id_no");       
    return user_id_check;
}

Session Class is implemented as

public class SessionClass : System.Web.UI.Page
{
     public bool check(string sessionName)
     {
         if (Session[sessionName] == null)
             return false;
         return true;
     }
}

But I am getting exception.

HResult=-2147467259 Message=Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration.

But in my web.config

<sessionState mode="InProc" timeout="30" />

I have also went through some question

@Div from `4th no SO link` in accepted answer says to configure any one `enableSessionState="true"` or `sessionState mode="InProc" ` and I have done the secondnd one. — R.A.Munna, Dec 15 '17 at 06:39

Have you ever tried this?

using System.Web.SessionState;

public class SessionClass :  IRequiresSessionState
{
     public bool check(string sessionName)
     {
         if (HttpContext.Current.Session[sessionName] == null)
             return false;
         return true;
     }
}

I have tried your suggest and getting this error `"Object reference not set to an instance of an object."` – R.A.Munna Dec 15 '17 at 09:51
Can you debug because there is no code line in the snippet to raise such error message. – Mike Dec 15 '17 at 10:01

you need to enableSessionState in your config as exception says

 <system.web>
      <pages enableSessionState="true" /> 
 </system.web>
