alt Hacker NewsNo they don't. I tried Chrome, Firefox, and Safari. None of them attempted to redirect. They just show a "not secure" warning in the URL bar.
The redirect only happens when it's configured on the web server, set in HSTS, or on a TLD that enforces HTTPS. None of these apply to this website.
Apparently it's not on by default, but all of my browsers do and also warn me whenever a site does not support HTTPS (and require me to explicitly click through to the unencrypted connection).
