Node.js http-proxy drops websocket requests

Question

Okay, I\'ve spent over a week trying to figure this out to no avail, so if anyone has a clue, you are a hero. This isn\'t going to be an easy question to answer, unless I am

I agree with hexacyanide. To me it would make the most sense to queue workers through a service like redis or some kind of Message Query system. Workers would be queued through Redis Pub/Sub functionality by web nodes(which are proxied). Workers would callback upon error, finish, or stream data in realtime with a 'data' event. Maybe check out the library kue. You could also roll your own similar library. RabbitMQ is another system for similar purpose.

I get using socket.io if you're already using that technology, but you need to use tools for their intended purpose. Redis or a MQ system would make the most sense, and pair great with websockets(socket.io) to create realtime, insightful applications.

Session Affinity(sticky sessions) is supported through Elastic LoadBalancer for aws, this supports webSockets. A PaaS provider(Modulus) does this exactly. Theres also satalite which provides sticky sessions for node-http-proxy, however I have no idea if it supports webSockets.
