* Disabled all methods of HTTP fallback when HTTPS is enabled. This is enforced on server side so that even modified client code (JS) can not redirect client from HTTPS to HTTP, like it was possible before (issue #355). * Current solution unfortunately also disables automatic upgrade from HTTP to HTTPS (when available), since all non-SSL connections are droped immediately.
