--- Comment #2 from Michael Osipov <micha...@apache.org> --- https://tools.ietf.org/html/rfc7230#section-6.1 says: The Connection header field's value has the following grammar: Connection = 1#connection-option connection-option = token Connection options are case-insensitive. As for the substring part: "close2" token is not "close". As per defition, only one token is allowed, so "close, close2" ist not valid. I see this as a valid point. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
