I need to implement a livestream video page (via Vimeo) that requires three versions of the pages: pre-event, during/live, and post-event. A countdown timer will live on the pre-event page, and once the timer is up, the page needs to refresh/redirect to populate the "during/live" page (this page will have the Vimeo video embedded). Once the livestream video is over, the page then needs to refresh once again to populate the post-event content. Does anyone know how this can be done? I can find third-party plugins for countdown timers but I'm struggling with how to implement the refreshing/redirecting of content/pages. Any help is much appreciated!
