Stomp
A STOMP frame is a STOMP 1.2 replacement for the CONNECT frame, used to start a STOMP session on a web socket connection.
Clients that use the STOMP frame instead of the CONNECT frame will only be able to connect to STOMP 1.2 servers (as well as some STOMP 1.1 servers) but the advantage is that a protocol sniffer/discriminator will be able to differentiate the STOMP connection from an HTTP connection.
