JavaScript Implementation Force redirection to HTTPS page _javascript tips

Sometimes you need to force the page to switch to HTTPS, even if the user has already accessed the HTTP version. The reason may be that you do not want the user to use HTTP for access because it is not secure. To do this is very simple, if you do not want to use PHP or Apache mod_rewrite to do this thing, with JavaScript can also. 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>

With this code, if a user accesses a http://leonax.net/..., it is redirected to https://leonax.net/... If you want to, in turn, Force HTTPS redirection to HTTP, change the value of Targetprotocol to HTTP. Is it convenient?
