same-origin with unencrypted connections on port 80. However, if a second encrypted port on the same IP address (e.g. port
8443) did not opt-in to opportunistic encryption; a network attacker
could forward a connection from the browser from port 443 to port 8443,
causing the browser to treat the content of port 8443 as same-origin
with HTTP. As a result, a remote attacker can bypass Same-Origin-Policy on services hosted on other ports.
