I'm not to happy with this change though. At least with hixie-76, connections would fail to connect if the intermediate proxies are not understanding WebSockets. Now, your connection will succeed, both client and server will believe they can successfully communicate, but communication will not work and die a slow timeout. Not very reliable, is it ?
