Proxy flash socket policy requests

[robertothais]

Some libraries such as socket.io can fall back Flash based sockets when the client does not support WebSockets. To achieve this, the client's Flash program first needs to request a 'socket policy file' from the server. This request consists of a self-closing XML node followed by the null byte sent over raw TCP:

<policy-file-request/>\0

node-http-proxy will drop this request, causing the Flash socket connection to fail.

Just run this wonderful thing here on your proxy server! Pretty much, it looks like this:

var pf = require('policyfile');
pf.createServer().listen();

And then all of your problems should be solved, almost like magic. (Socket.io uses this library for it's Flash Policy File Server as well)

@rthais Works this lib for you?

@rthais @coderarity can we close this?

[robertothais]

Yes, that works. I think we can close this issue.

For anyone visiting this thread later with the same question - the code that worked for me is:

var pf = require('policyfile');
pf.createServer().listen(null,server);

where server is the server you already created via http.createServer().

does this work today?

There is a problem with non 80 ports on nodejitsu right?
https://www.nodejitsu.com/documentation/a-quickstart/faq/#how-can-i-make-my-app-use-a-port-other-than-port-80

Is there any chance to have it running on nodejitsu?

@konklone I followed your instructions for policyfile but I get an error that the address is in use. I have been going in circles with this for a bit. Any help would be greatly appreaciated

var express = require('express');
var app = express();
var server = require('http').createServer(app).listen(process.env.PORT || 9009);
app.use(express.static(__dirname + '/public'));
var pf = require('policyfile').createServer().listen(null, server);
var io = require('socket.io')({
  transports: ['websocket']
}).listen(server);

[konklone]

@dvideby0 It sounds like you might already have an instance of the server running in some other terminal?

[dvideby0]

@konklone Unfortunately no and the code I put above fails all on its own (without any other logic). Not sure if there is something additional I am supposed to add but I should probably point this issue to the author. Thank you for the help sir!
