我该如何阻止https

Question

I have a website that can be accessed both with http and https. The website has a form that brings the user to another site on another server. So when I use https and the form is submitted, I get a warning that the data are being sent insecurely.

The second server does not support https, so I figured that the fastest and easiest is to prevent the first website from being accessed through https.

Is there a way to do that (with PHP for example)?

Answer 1

All you have to do in this case is check the HTTPS status on your form page, and redirect to HTTP if necessary:

if (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') {
    header('Location: http://' . $_SERVER["SERVER_NAME"] . $_SERVER['REQUEST_URI']);
}
