Cookies in a shopping cart

Question

How to allow cookies in a shopping cart so that the customer can be able to view items in the cart that he/she did add into the cart, I did try something like this

 

// We're using HttpContextBase to allow access to cookies.

public string GetCartId(HttpContextBase context)

{

if (context.Session[CartSessionKey] == null)

{

if (!string.IsNullOrWhiteSpace(context.User.Identity.Name))

{

context.Session[CartSessionKey] =

context.User.Identity.Name;

}

else

{

// Generate a new random GUID using System.Guid class

Guid tempCartId = Guid.NewGuid();

// Send tempCartId back to client as a cookie

context.Session[CartSessionKey] = tempCartId.ToString();

}

}

return context.Session[CartSessionKey].ToString();

}
