JavaScript implements forced redirection to HTTPS page_javascript skills

Sometimes it is necessary to force a web page to switch to HTTPS, even if the user has already accessed the HTTP version. The reason may be that you don't want users to use HTTP for access because it is not secure. It's very simple to do this. If you don't want to use PHP or Apache's mod_rewrite to do this, you can also use Javascript. The code is as follows:

<script type="text/javascript">
var targetProtocol = "https:";
if (window.location.protocol != targetProtocol)
 window.location.href = targetProtocol +
  window.location.href.substring(window.location.protocol.length);
</script>

Using this code, if the user visits such as http://leonax.net/…, he will be redirected to https://leonax.net/… .. If you want to do the opposite, that is, force HTTPS to redirect to HTTP, just change the value of targetProtocol to http. Isn't it very convenient?
