Could websocket support gzip compression?

Question

After the success handshake of WebSocket, could we used gzip compression?

Here are my tests:

1. I use autobahn lib to build a server, then respon to cli

Answer 1

There is a compression extension being worked on by the IETF Websocket (HyBi) working group. I would suggest following their mailing list for up-to-date information. I also recommend checking out this question.

Update 2017: The extension has now been available for some time, see here: https://tools.ietf.org/html/rfc7692
