Is there a plugin or some other way to check to see if a website has https available, and use that instead? I know some sites, like Wikipedia have a different hostname for SSL support (
https://secure.wikimedia.org/wikipedia/), while others have the same hostname, just https:// intstead of
http://. What I would really like to see is some kind of header in the http reply or the html that says SecureAvailable="https://thesitename.com", is there any system like this in place? There's too many issues with with unencrypted http to continue having that as the default.
