I have set hsts for my domain on the site http://server.mydom.tld:80, so the brower goes to port https://server.mydom.tld on port 443
However, I also have other webservers, running on other ports. So when I go to http://server.mydom.tld:8888 it gets forwarded to https://server.mydom.tld:8888, but that server does not run https, so the request fails.
Is that according to spec?
I noticed I don't run hsts on http://mydom.tld or http://www.mydom.tld, which is probably a mistake.
What to do?
