Linux web servers that support websockets?

  • 772

I'm currently having a lots of difficulties trying to play with socket.io which needs websockets support from the server (reverse-proxying).

I was wondering, is there any other web servers out there that supports websockets?

The errors I'm having with nginx:

2012/05/22 02:19:34 [error] 28159#0: *5 connect() failed (111: Connection refused) while connecting to upstream, 
client: my.ip.ad.dr,
server: localhost,
request: "GET /socket.io/1/?t=1337653158192 HTTP/1.1", 
upstream: "http://127.0.0.1:3000/socket.io/1/?t=1337653158192", 
host: "lifestore.brainpad.org", referrer: "http://mywebad.dr/"
web-server nginx socket

  1. nginx doesn't natively support websockets. Looks like there is a tcp proxy module that can be compiled into nginx to do this.

    But a few other discussions(here and on SO) seem to indicate that one would go down to node.js directly.

    Given that you're using socket.io, I suspect you're already using node.js on the backend. Also, this blog post by the trello team is rather informative. http://blog.fogcreek.com/the-trello-tech-stack/

  2. nginx has support for proxying WebSockets since version 1.3.13.

    The only thing I've found so far that could conceivably be called documentation is this commit message.
