contentLength and ReadMaxPayloadSize mismatch

[prawnsalad]

I'm trying to verify the ReadMaxPayloadSize config option but i can't quite make sense of it.

In readMessage() if I add print("contentLength = ", contentLength, " continuation? ", opcode == OpcodeContinuation, "\n") and then use this test script in Chrome:

w = new WebSocket('ws://localhost:5000/connect');
w.addEventListener('open', () => w.send('a'.repeat(1024)));

I would expect contentLength to be 1024. However, it prints contentLength = 11 continuation? false. Is there some unit mismatch or is it reading the contentLength incorrectly?

Post the gws server configuration

gws.NewUpgrader(wsHandlers, &gws.ServerOption{
		ReadAsyncEnabled: true,         // Parallel message processing
		CompressEnabled:  true,         // Enable compression
		Recovery:         gws.Recovery, // Exception recovery
		ReadMaxPayloadSize: 1024,
		Logger: lt{},
	})

The content is compressed

Ahh of course.. that makes sense! So ReadMaxPayloadSize is the protocol level max payload size. Now it makes sense and everything is good. Thank you!
