About the example code

[Pana]

var sticky = require('sticky-session');

var server = require('http').createServer(function(req, res) {
  res.end('worker: ' + process.env.NODE_WORKER_ID);
});

if (!sticky.listen(server, 3000)) {
  // Master code
  server.once('listening', function() {
    console.log('server started on 3000 port');
  });
} else {
  // Master code
}

I think the else code should be worker code, and process.env.NODE_WORKER_ID is undefined in my node 4.0 version

Argh, it should be NODE_UNIQUE_ID for the 4.x. May I ask you to file a Pull Request for this change?

[indutny]

Thanks!

When i use the NODE_UNIQUE_ID still got undefined, but i have find this in node cluster doc

True if the process is a master. This is determined by the process.env.NODE_UNIQUE_ID. If process.env.NODE_UNIQUE_ID is undefined, then isMaster is true.

I believe it would be very useful to include an actual socket listener in the README Worker-example. @indutny
