Server side usage – VB

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.

VB

Imports System.Web.Script.Serialization
...

Dim CurrentUserConsent As HttpCookie = Request.Cookies("CookieConsent")

If CurrentUserConsent IsNot Nothing Then
Select Case CurrentUserConsent.Value
Case "0"
REM The user has not accepted cookies - set strictly necessary cookies only
Exit Select

Case "-1"
REM The user is not within a region that requires consent - all cookies are accepted
Exit Select

Case Else REM The user has accepted one or more type of cookies

REM Read current user consent in encoded JavaScript format
Dim CookieConsentSerializer As New JavaScriptSerializer()
Dim CookieConsent As dynamic = CookieConsentSerializer.Deserialize(Of Object)(HttpUtility.UrlDecode(CurrentUserConsent.Value))

If CookieConsent("preferences") Then
REM Current user accepts preference cookies
Else
REM Current user does NOT accept preference cookies
End If

If CookieConsent("statistics") Then
REM Current user accepts statistics cookies
Else
REM Current user does NOT accept statistics cookies
End If

If CookieConsent("marketing") Then
REM Current user accepts marketing cookies
Else
REM Current user does NOT accept marketing cookies
End If
End Select
Else
REM The user has not accepted cookies - set strictly necessary cookies only
End If
