Followup to bug 965413. I'm guessing Tanvi or Christoph may actually be the most logical people to fix this, as they're touching all this code very soon and know the landscape well.
Depends on: 965413
Interesting, this is actually one of the cases which bug 1038756 wouldn't fix, because the channel is not created through NS_NewChannel, but rather by calling NewChannelFromURIWithProxyFlags directly on the ioservice. Anyway, we can set the LoadInfo on that channel manually right after the channel is created [1]. Creating dependency to bug 1038756 anyway, because they are so closely related.

Providing a WIP patch to start the discussion: I think it's best if we manually set the loadInfo right after channel creation in the WebSocketChannel. Here are the remaining questions/thoughts: In WebSocket::Init() we set mPrincipal, what if we also create and set mDocument, which would be the |originDoc| we use to call ContentPolicies [1]. Later in AsyncOpen [2], we could "eventually" use the |aContext| argument to pass that information. Currently aContext is always a nullptr, what sideEffects would that cause here [3]. It would be great to have the requestingContext (node) in addition to the principal, especially to handle redirects for MCB correctly. Finally, what do we do for e10s? Passing a nullptr as the principal is not that great :-( [1] http://mxr.mozilla.org/mozilla-central/source/content/base/src/WebSocket.cpp#724 [2] http://mxr.mozilla.org/mozilla-central/source/netwerk/protocol/websocket/WebSocketChannel.cpp#2663 [3] http://mxr.mozilla.org/mozilla-central/source/netwerk/protocol/websocket/WebSocketChannel.cpp#2828

(In reply to Christoph Kerschbaumer [:ckerschb] from comment #2) > Created attachment 8472641 [details] [diff] [review] > bug_1037669_loadInfo_on_websockets.patch The websocket channel is created with do_createInstance here - http://mxr.mozilla.org/mozilla-central/source/content/base/src/WebSocket.cpp#781. We should add loadInfo to the wschannel in EstablishConnection(). Then when AsyncOpen is called, a local http channel is used to bootstrap the connection: http://mxr.mozilla.org/mozilla-central/source/netwerk/protocol/websocket/WebSocketChannel.cpp#2769 We can pull the loadinfo from wschannel and use it for the localchannel.

That seems reasonable - here we go.

Since we are getting closer to land 1038756, we can also get that patch reviewed, which can land right after the patch series of bug 1038756.

Whenever I base some comments/code on other comments/code already in that file something like this happens. Updated both comments :-)
