Is it possible to redirect an HTTPS request without a domain certificate to another domain with HTTP?

Question

Nginx

Is it possible to make a redirect from https://host1/ to host2 in the default settings of the nginx host without having the host1 certificate?

Answer 1

No. The browser will swear at the user's face.
There are services that provide free certificates. You can ask your hoster. I don't remember the name. FreeSSL google.

Answer 2

Redirect is not possible.
Proxy is possible.

Answer 3

Nothing is possible without a certificate. If it's only a matter of a certificate and you need a world-recognized one - LetsEncrypt, if you don't care about recognition - release it yourself (in this case, you can StartSSL, if it's still alive of course). Well, you can always buy a certificate :)
