Igor GolbrodskiyMethod :sendText and message mask
on Tue, 23 May 2017 12:30:52 +0300
Hi Alaska-team.
I have troubles with WinSocketClient:sendText().
It works fine if a client and a server is written in  Xbase++.
But when my client program communicates with another websocket service, 
which was written in Java and deployed from TomCat, it doesn’t work.
I found out that the main cause is that the method sendText never applies 
mask for the sending message.
But, according RFC 6455 a client MUST mask all frames that it sends to the 
server.
Is it a mistake or a feature?

Many thanks in advance.

Sorry, I've done small mistake.
I mean WebSocketClient instead of  WinSocketClient. And one addition, the 
server port isn't 443

You can easily test this using the free evaluation version of Xb2.NET 
(http://xb2.net/xb2net/).

Download the Xb2.NET ZIP file, run GO.BAT to compile all samples, then run 
the WSCLIENT.EXE sample from a command prompt with your WebSocket server 
endpoint as a param, eg:

WSCLIENT wss://xb2.net/echo
