number number is an op code indicating the type of web socket frame. Numbers 0-7 are non-control frames. Numbers 8-15 are control frames. Control frames are always sent immediately and cannot be fragmented. Specifying a reserved code will cause immediate request cancellation.
0 A continuation frame. A continuation frame is treated as text or binary based on the op code of the first frame. A continuation frame cannot also be the first frame.
1 A text frame. Text frames are are translated to ASCII with the translate table in effect for the port.
2 A binary frame. No translation is done for binary frames.
3-7 Reserved for future use and will cause request cancellation.
8 Connection close frame.
9 Ping. The receiver should respond with a Pong frame, unless a close frame has been received.
10 Pong. This is sent as a response to a Ping frame.
11-15 Reserved for future use and will cause request cancellation.
128 This value is added to the frame op code to indicate the final fragment of a non-control message. The first fragment may also be the final fragment.
