www self-signed

[akirataguchi115]

https://mooc.fi/ works fine and it redirects to https://www.mooc.fi/

https://www.courses.mooc.fi/ does not work fine since the cert is self-signed

should the latter have a properly signed cert or should it redirect to https://courses.mooc.fi/ ?

Hi,

It is not common to use the www prefix with subdomains. www is a subdomain, just like courses, and adding a subdomain in front of another subdomain offers no advantage. That’s why the convention of adding www before domains has never applied to subdomains.

While it is not ideal for the URL to serve a self-signed certificate, I think it should still trigger an error.

-or it could just redirect to courses.mooc.fi since other non-technical people have/will continue to link courses.mooc.fi with the www prefix.
