Reducing the lifespan of the CookieConsent cookie

By default the cookie that remembers a user's consent (CookieConsent) has a lifespan of 12 months.

If you would like to reduce (or increase, but this isn't recommended) the cookie's lifespan, you can do so by adding this script to the page:

<script type="text/javascript">
  window.addEventListener("CookiebotOnLoad", function() {
    var consentDate = new Date(CookieConsent.consentUTC),
      checkDate = new Date();

    checkDate.setDate(checkDate.getMonth() - 6);

    consentDate < checkDate && (CookieConsent.deleteConsentCookie(), CookieConsent.show());
</script>

This will reduce the lifespan to 6 months. You can also specify days instead of months by using checkDate.setDate(checkDate.getDate() - 7);
In this example the cookie is deleted after a week.

If you want the banner to ask for consent on every visit, you can also make the CookieConsent cookie sessions based. This means that the consent settings will be forgotten when you close the browser.
This is useful if you have a device used by several users:

<script type="text/javascript">
  window.addEventListener("CookiebotOnLoad", function() {
    var cookies = document.cookie.split(";");

    for (i of cookies) -1 != i.indexOf("CookieConsent") &&
        (document.cookie = i + ";path=/");
  }, false);
</script>
