SimpleAsyncHTTPClient
accepts a customresolver
instance, and this can be used to make an HTTP connection to Unix sockets (see also #2671). I would like to do the same with WebSocketClientConnection. It's possible by globally configuring the resolver class, but I'd prefer to do it without global side-effects.For more context, this is part of an effort for jupyter-server-proxy to support proxying services listening securely on Unix sockets, as well as TCP sockets (jupyterhub/jupyter-server-proxy#337 ). This is currently working apart from Websocket support, which this PR would make possible.
