Injecting data into every request

I have a situation where I need to generate an ID in javascript and put it into the masterpage somehow so that every time a request gets back to a controller I can get that value in the controller. I need this to work whether the request be from a form submit, or ajax call etc. In the controller I will have a property with a getter that pulls that value out of the masterpage somehow. Is this possible and how would it be achieved?

Use cookie in client and get you can get value from controller.

  1. Write a base controller and extends that controller in your controller.

  2. Write method in base controller to read cookie and store a variable. you can access the variable from derived controllers.

See below example:

  public class BaseController : Controller
    {
        private string _id = null;
        protected string ID
        {
            get
            {
                var cookie = Request.Cookies.Get("ID");
                if (cookie != null)
                {
                    _id = cookie.Value;
                }

                return _id;
            }
        }
    }

        public class HomeController : BaseController
        {
            public ActionResult Index()
            {
                var test = ID;

                ViewBag.Title = "Home Page";

                return View();
            }
        }

// Place below code in your master page...

 <script>
        function setCookie(cname, cvalue, exdays) {
        var d = new Date();
        d.setTime(d.getTime() + (exdays*24*60*60*1000));
        var expires = "expires="+ d.toUTCString();
        document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
        }
        setCookie("ID", "123456", 1);
    </script>
