I've used http://www.com for that.

Same here! Yes, I used it as the well-known site that supported unencrypted http and no HSTS. Yes, I was one of those guys using the site "as a service" rather than simply documentation. Admittedly, it was perhaps interchangeable with other sites, but since it reliably worked for that purpose, I couldn't be arsed to find other ones.

Isn't there a dedicated site called nohttps or something? NeverSSL? I just tried http NeverSSL, and it redirected me to an https page with a random hostname and an Amazon SSL certificate!

Does example.com still function this way, with http and no HSTS? I noticed that my Chrome browser was immediately redirected in the customary way.

http://neverssl.com/online/ seems to work for me?

Are you perhaps on an untrusted network which is spoofing that url to make it redirect somewhere else?

reply
No, NeverSSL changed to have SSL a while back - around the time that Chrome/Firefox started throwing big warning signs and/or blocking non-https pages.
reply
Wait, are you saying neverssl.com now sometimes uses SSL?

If this is a joke, it's over my head. If not, I'm not knowledgeable enough in this space to pass judgement, but that would seem crazy to me. Like the owner should consider a domain name change :)

reply
It has SSL on the main domain, and some subdomains without SSL (wildcard perhaps?). The main domain (when accessed over SSL?) redirects to a subdomain with plain HTTP.

Kinda weird setup!

Edit: okay, the subdomains also have SSL. I guess the random subdomain thing is to make sure it hasn’t been cached in a “this site has HTTPS” list. The HTTPS is needed, of course, to please the browser makers, as the parent says.

http://http.rip/ is one I use

Wow finally, a "no ssl" site that actually doesn't use SSL! I was so disappointed when "NEVERssl" added SSL, like you literally have ONE job. Some clients automatically upgrade http->https or prepend https if left unspecified, so it's nice to have an explicitly HTTP-only (IE port 80-only) service for testing/captive portals.

This is very useful, thanks for sharing!

My browser (iOS safari) just takes me to the ssl version from that link, so “never ssl” seems wrong?
reply
http://example.com/ works for me in Safari, warning that the site is “not secure”, but only if I type it in by hand.
