Server side usage – C#

If your website is setting cookies server side, you can determine what type of cookies you are allowed to set by checking the users current consent state through standard cookie handling.

C#

using System.Web.Script.Serialization;
...

HttpCookie CurrentUserConsent = Request.Cookies["CookieConsent"];

if (CurrentUserConsent != null)
{
    switch (CurrentUserConsent.Value)
    {
        case "0":
            //The user has not accepted cookies - set strictly necessary cookies only
            break;

        case "-1":
            //The user is not within a region that requires consent - all cookies are accepted
            break;

        default: //The user has accepted one or more type of cookies

            //Read current user consent in encoded JavaScript format
            JavaScriptSerializer CookieConsentSerializer = new JavaScriptSerializer();
            dynamic CookieConsent = CookieConsentSerializer.Deserialize<object>(HttpUtility.UrlDecode(CurrentUserConsent.Value));

            if (CookieConsent["preferences"])
            {
                //Current user accepts preference cookies
            }
            else
            {
                //Current user does NOT accept preference cookies
            }

            if (CookieConsent["statistics"])
            {
                //Current user accepts statistics cookies
            }
            else
            {
