/* If a WS session contains sensitive information, and you choose to use
cookies for authentication (during the HTTP(S) upgrade request), then
you should check that Origin is a domain under your control. If it
isn't, then it is possible for users of your site, visiting a naughty
Origin, to have a WS opened using their credentials. See
http://www.christian-schneider.net/CrossSiteWebSocketHijacking.html#main.
We don't care about Origin because the (IRC) authentication is contained
in the WS stream -- the WS session is not privileged when it is opened.
