ASP MVC Cookies not persisting
The problem lies in following code:
if (System.Web.HttpContext.Current.Response.Cookies["CountryPreference"] == null)When you try to check existence of a cookie using Response object rather than Request, ASP.net automatically creates a cookie.

The short explanation, if you don’t like to read the entire story
If you use code like “if (Response.Cookies[“mycookie”] != null) { … }”, ASP.Net automatically generates a new cookie with the name “mycookie” in the background and overwrites your old cookie! Always use the Request.Cookies-Collection to read cookies!
