Detailed Description

An implementation of the WebSocket protocol...

This currently passes all 303 Autobahn test suite conformance and performance tests (1.* -> 10.*) with only 3 'non-strict' passes (6.4.2, 6.4.3 and 6.4.4).

Note
When not in testing mode, connections will be closed if a frame larger than 1MB or a message larger than 4MB is received.

◆ Close

void MythWebSocket::Close ( )
slot

Initiate the close handshake when we are exiting.

Note
This is intended to be used when the server or client connection is exiting and we want to be a good netizen and send a proper close request. There is however no expectation that the socket will remain open to complete the close handshake; and thus the close will likely be 'unclean'.
