HTTP headers in Websockets client API

Looks like it's easy to add custom HTTP headers to your websocket client with any HTTP header client which supports this, but I can't find how to do it with the JSON API.

Yet, it seems that there should be support these headers in the spec.

Anyone has a clue on how to achieve it?

var ws = new

Specially, I need to be able to send an HTTP Authorization header.



There is no existing method in the JavaScript WebSockets API for specifying additional headers for the client/browser to send. The only headers that the client can influence are the resource-name/path (in the URI) and the WebSocket-Protocol header. The WebSocket-Protocol header is generated from the optional second argument when a WebSocket object is created:

var ws = new WebSocket("ws://example.com/path", "protocol-name");
