httpsRedirect

Redirects the page to HTTPS if its currently in HTTP. Also, pressing the back button doesn't take it back to the HTTP page as its replaced in the history.

const httpsRedirect = () => {
	if(location.protocol !== "https:") location.replace("https://" + location.href.split("//")[1]);
}
