Redirect a user from HTTP to HTTPS using JavaScript

Tweet

Although a redirection is best done using your webserver or server-side code (for SEO purpose), here’s a simple way to redirect a page from Http to Https using JavaScript

<script type="text/javascript">
    if (window.location.protocol == "http:") {
        var restOfUrl = window.location.href.substr(5);
        window.location = "https:" + restOfUrl;
    }
</script>

If you want to avoid the back button as a result of the redirection, check this post of mine
