Hi,
is it possible to limit the frame size of WebSocket messages sent from Undertow? I
didn't find anything related in the configuration or options.
Thanks,

They the maximum size is determined by the buffer size (although this refers to individual
frames, you can still send larger messages using continuation frames).

Hi Stuart,
that's what I'm trying to do, sending large messages that consist of multiple
frames.
By buffer size do you mean this option:
Undertow.builder().setBufferSize(1024)....?
Because this doesn't work for me, the message (larger than 1024 bytes) is always
transferred in one frame.
Maybe you can provide an example how to do this correctly?
Thanks, Dominik

How are you using websockets?
If you are using the JSR-356 API and deploying using WebSocketDeploymentInfo you need to
change the buffer size for outgoing connections in the setBuffers() call:
new WebSocketDeploymentInfo()
.setBuffers(new DefaultByteBufferPool(true, 1024))
Otherwise the buffer size from the Undertow builder should be used. Can you provide an
example of that you are doing?

Basically we are using Undertow as shown in the ChatServer example
(https://github.com/undertow-io/undertow/blob/master/examples/src/main/jav...)
i.e. no JSR-356 API. With the small difference that we are sending binary data and we set
a buffer size using the Undertow builder. As Websocket client we are using the
AsyncHttpClient (https://github.com/AsyncHttpClient/async-http-client) which then fails
receiving messages larger than the set buffer size with an exception saying "Max
frame length has been exceeded.". Example code here:

Ah, looks like I forgot about a relatively recent optimization that was added. A new
method (AbstractFramedStreamSinkChannel.send) was added that allows you to send the whole
contents of a buffer in one frame (which prevents double copying into the internal stream
buffer). The WebSockets utility methods have been changed to use this method.
If you use the write() method instead of send() then it will use the internal buffer which
will limit the frame size to the internal buffer size (have a look in
io.undertow.util.StringWriteChannelListener for an example of how to use this).
