Access WebForms ASPX Page Session in ApiController

I am trying to access the Session in Controllers which are part of a webform project. All the session variables are set on ASPX pages 

Session["SESSION_KEY_UI_CULTURE"] = ddlLanguage.SelectedValue;

Now on API request from client i need to read Session Variables and perform a task but Session is always null.

[RoutePrefix("api/accounts")]
    public class AccountsController : ApiController
    {
        [Route("config")]
        [HttpGet]
        public IHttpActionResult GetCompanyConfig()
        {
            if(HttpContext.Current.Session != null)
            {
                //Session is always NULL
            }

            return Ok();
        }
    }

I have tried removing and adding SessionStateModule in WebConfig file

<remove name="Session" />
<add name="Session" type="System.Web.SessionState.SessionStateModule"/>

ASP.NET Web Api is meant for REST Services which are by definition stateless. Adding the Session back into Web Api defeats the purpose of having a RESTful API. You may want to reconsider what you're trying to achieve and find another way to solve your Problem.

But there is a way to do what you want:

To activate Session nontheless add the following to your Global.asax

C#

protected void Application_PostAuthorizeRequest() {
 HttpContext.Current.SetSessionStateBehavior(SessionStateBehavior.Required);
}

VB

Sub Application_PostAuthorizeRequest()
    HttpContext.Current.SetSessionStateBehavior(SessionStateBehavior.Required)
End Sub

Here and here are 2 Topics that are going into the same direction which you might want to look at for further information
