In ASP.NET MVC, a field which is declare outside a method, the field is initialize every-time.

There I am giving a demo example.

public class TestController : Controller
{

    private List<object> ListItems; 
    // GET: /Test/Index
    public ActionResult Index(int Id)
    {
        ModelSource _model = new ModelSource(Id);
        ListItems = _model.GetItems();//coming info from Model
        return View();
    }


    // GET: /Test/Demo
    public ActionResult Demo()
    {
        int x  = ListItems.Count;
        //Do Something More
        return View(x);
    }
}

Is It possible for ListItems will be initialize for once for every client as Id parameter will be different on client's request.

As Patrick Hofman stated you can use Sessions or Cookies Here is an example for both:

Cookies: 

 string cookievalue ;
 if ( Request.Cookies["cookie"] != null )
 {
    cookievalue = Request.Cookies["cookie"].ToString();
 }
 else
 {
    Response.Cookies["cookie"].Value = "cookie value";
 }
//For removing cookie use following code

if (Request.Cookies["cookie"] != null)
{
    Response.Cookies["cookie"].Expires = DateTime.Now.AddDays(-1);   
}

Sessions:

HttpContext.Current.Session.Add("Title", "Data"); 

string foo = Session["Title"];
