WebSocket and host-rules Switch

[jhleath]

I am grateful for you adding support for the --host-rules command line switch; however, the addition of this tag seems to have introduced errors involving the resolution of websockets (ws://) domains.

It appears as though when the host rules switch is active for a domain, websockets requests to that domain never complete (they stay pending forever, without contacting the server). I have concluded that they cannot successfully resolve the name.

I have experimented with Atom-Shell and Chrome proper, and Chrome will correctly handle the websockets request with the host-rules flag, while Atom-Shell will only load the websocket if it doesn't include the host-rules url (i.e. switching to xip.io). Thanks for all your help!
