Sending custom headers

[gciluffo]

I see there are multiple PR's for adding custom request headers. However, whenever I try sending up custom headers with this library in angular I cant seem to get any message to the client when I do client.send("Testing!"). Even though it is making the connection.

However it seems to work just fine when I dont send up any headers. Has anyone run into this issue before?

Client:

this.eventSource = new EventSourcePolyfill('http://localhost:3000/sse', 
    { headers: 
      { 'Authorization': `Bearer ${localStorage.getItem('token')}`, 
        'ocp-apim-subscription-key': environment.worklistApiSubKey }
    });

Server:

export function initializeSSE(server: Server) {
  sse = new SSE(server);
  sse.on('connection', (client: any) => {
    log.info(`new clint connected ${client.req.url}`);
    client.send({data: 'Sup Kyle!'});
  });
}

Ive also added supporting for custom header on the initialization

SSEClient.prototype.initialize = function() {
  this.req.socket.setNoDelay(true);
  this.res.writeHead(200, {
    'Content-Type': 'text/event-stream',
    'Cache-Control': 'no-cache, no-transform',
    'Connection': 'keep-alive',
    'Access-Control-Allow-Origin': '*',
    'Access-Control-Allow-Headers': 'Authorization, ocp-apim-subscription-key'
  });
  this.res.write(':ok\n\n');
};
