Proxy configuration not used for websocket connections

[dguggemos]

Proxy configuration provided via environment variables seems not be used for websocket connections. This would however be very useful, especially in corporate environments where a proxy is in place.

Do you mean the WebSocket global?

[dguggemos]

I have configured the environment variables as described here: https://deno.land/manual/linking_to_external_code/proxies#proxies

Then I try to create a WebSocket connection (to an endpoint only accessible via proxy):

var ws = new WebSocket("ws://echo.websocket.org");

I noticed this missing proxy support also recently with the (Web Standard) WebSocket client of deno: https://doc.deno.land/builtin/stable#WebSocket

So probably this issue is not (yet) about the WebSocket server in "deno_std/ws".

@kitsonk should this issue be moved again to denoland/deno?

Currently the websocket library tungstenite doesn't support proxies, would have to wait for issue snapview/tungstenite-rs#177 to be resolved.

technically they use tokio_tungstenite however that's just a wrapper around tungstenite to make it async.

We do not use tungstenite anymore. We now use fastwebsockets. We should be able to add proxy support using the proxy handling that we also use for fetch.
