I realize I might be showing my ignorance here, but is there an HTTP/2.0 specification? I have a customer attempting to reach a web site and ISA is responding with a 502 error indicating that the request is not supported. My Cisco ASA passes the traffic though (not performing any application layer inspection!) and a network trace shows that the remote web server is responding with an HTTP/2.0 OK. Since I can't seem to find anything on the Internet regarding an HTTP/2.0 specification, I have to assume the ISA firewall is doing its job and rejecting this non-RFC communication, correct? Thanks!
