Add data send/receive progress call back to the Web Socket Client to keep track of total bytes and bytes sent.

I would be nice to add callback to the TWebSocketClient in WebCore to track the total bytes and bytes sent to be able to track when large data packets are being sent.

There is at this moment, as far as we can see, no universal & straightforward interface to catch this at browser level. We'll keep watching this if possible solutions / approaches appear.
