WebSocketConnection.Send exception "Buffer maximum length exceeded (18730 vs 16384)"

[deniszykov]

There is an artificial restriction on sending messages. The RFC6455 says nothing about such size of messages (http://tools.ietf.org/html/rfc6455#section-5.2). In addition, Send does not accept Streams, but only buffers and strings.

You can set the max message size on the server:

using (var server = new TcpServer())
{
    server.MaxIncomingQuota = 32768;
    server.MaxOutgoingQuota = 1048576;
}

Yeah, I didn't see a way to pass streams, which would be really useful.

Re streams: it should be pretty trivial to write an extension method (or
regular utility method) that loops a buffer over a stream; we could add it
as an API, of course.

Ah, I completely misread the Send() method. It initially appeared to me that it was always expecting a string, then converting that to a byte array of chars and adding to the frame/batch (I thought it was really weird you expected an object). I skipped over the code at the end where you check if its a string (and < the max frame size) or if it's a byte[]. Yeah, if I can pass a byte[] in than that mostly eliminates the need for a stream for me. Calling .ToArray() is hardly a big deal and having it sent as binary data isn't an issue for me.

It's interesting that text data requires multiple frames w/continuations but binary data doesn't.
