HTTP: connections with wrong ALPN protocols are now rejected. This is a recommended behavior by RFC 7301 and is useful for mitigation of protocol confusion attacks [1]. To avoid possible negative effects, list of supported protocols was extended to include all possible HTTP protocol ALPN IDs registered by IANA [2], i.e. "http/1.0" and "http/0.9".
