Brad Fitzpatrick 1237000efe control/controlhttp: don't assume port 80 upgrade response will work ... Just because we get an HTTP upgrade response over port 80, don't assume we'll be able to do bi-di Noise over it. There might be a MITM corp proxy or anti-virus/firewall interfering. Do a bit more work to validate the connection before proceeding to give up on the TLS port 443 dial.
