Setup iZooto push notifications on HTTPS website
Chrome, Firefox browsers require websites to be on HTTPS to take user subscriptions for web push notifications. While HTTPS sites can integrate web push SDKs and take subscriptions directly on their domain, HTTP websites have to follow approaches set by web push service providers they're using. The common approach followed by most of the service providers is taking subscriptions on their sub-domain. For example, with this implementation for an HTTP website http://trak.in, subscriptions would be taken on https://trak.izooto.com.
