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

Yes it could. Chrome 19+ supports it.

"https://github.com/crossbario/autobahn-python/blob/master/examples/twisted/websocket/echo_compressed/server_advanced.py"

from twisted.internet import reactor
from twisted.web.server import Site
from twisted.web.static import File

from autobahn.twisted.websocket import WebSocketServerFactory, \
    listenWS

from autobahn.websocket.compress import *

def accept(offers):
    for offer in offers:
        return PerMessageDeflateOfferAccept(offer)

debug = True
factory = WebSocketServerFactory(u"ws://127.0.0.1:9000", debug=debug, debugCodePaths=debug)
factory.setProtocolOptions(perMessageCompressionAccept=accept)

listenWS(factory)

webdir = File(".")
web = Site(webdir)
reactor.listenTCP(8080, web)

reactor.run()
