I have a method in AJAX that sends me a certain value, when so requested, for a session variable (a list of strings in this case).

Session Variable

private static List<string> ListData {
  get{return (List<string>) Session["ListDataSession"];}
  set {Session["ListDataSession"]=value;}

}

AJAX Method

 $.ajax({
        type: "POST",
        url: "Teste.aspx/UpdateData",
        data: '{name: "' + "newValue"+ '" }',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: OnSuccess,
        failure: function(response) {
        }
    });

C # method

[System.Web.Services.WebMethod]
public static bool UpdateData(string name)
{
    UpdateData.Add(name);
    return true;
}

How to make this single session variable in this type of cases where I need to have declared a static variable to manage information coming via AJAX?

This issue arises because opening two tabs where the same variable is used can not guarantee the integrity of the data.

I believe it would work that way

private List<string> ListData 
{
get {return (List<string>) HttpContext.Current.Session["ListDataSession"];}
set {HttpContext.Current.Session["ListDataSession"]=value;}

}

In your C # method

[System.Web.Services.WebMethod(EnableSession = true)]
public static bool UpdateData(string name)
{
  UpdateData.Add(name);
  return true;
}

It is never good to use static properties in this case, because if two users are accessing the application at the same time they will access the same data.
