Setting up Session State in MVC

In Global.asax.cs add:

        protected void Session_Start(object sender, EventArgs e)
        {
            // Code that runs when a new session is started
            if (HttpContext.Current.Session["SearchSettings"] == null)
            {
                HttpContext.Current.Session["SearchSettings"] = 
new SearchSettingsModel
                {
                    DefaultSearchKeyword = "Microsoft", 
                    QueryServiceUrl = "http://spsite/_vti_bin/search.asmx" };
            }
        }

Then in SearchController.cs put:

        public ActionResult SearchSettings()
        {
            var settingsModel = ControllerContext.HttpContext.Session["SearchSettings"] 
as SearchSettingsModel;

            return View(settingsModel);
        }

        [HttpPost]
        public ActionResult SearchSettings(SearchSettingsModel model,
 string returnUrl)
        {
            if (ModelState.IsValid)
            {

            }

            // If we got this far, something failed, redisplay form
            return RedirectToAction("SearchSettings");
