It's not supported in any browser, so good luck using it on the web. Even more, the semantics for such a URL as defined by RFC6784 means that common HTTP features like redirects can't work: client sends a request to
http://[fe80::6%7], the User Agent sends a request to server with "Host:
http://[fe80::6]", and receieves a 302 response with "Location:
https://[fe80::6]" . What can client do next?
