I added preloader to my website which runs with ruby on rails, it seems it works perfectly, but because of pusher websockets, preloader does not end, it waits all the time, i tried this at my footer,
<script>
window.paceOptions = {
ajax: {
trackWebSockets: false,
ignoreURLs: [/pusher/, /heap/]
}
}
</script>
but it did not work. how can I solve this problem?
