node.js responds twice

Question

node.js responds twice

I've got a strange behavior with my fresh install of node ( from git ) on a debian machine. It seems that the problem is not in my code, cause everything is working good on windows. I already know that's it's not a favicon problem.

here is what I wrote :

var app = require('express')()
  , server = require('http').createServer(app)
  , io = require('socket.io').listen(server) 
  , url = require('url')
  , qs = require('querystring')
  , request =  require('request')
  , fs = require('fs')

followed by

server.listen(3000); 
app.post('/postReload', function (req, res) {
  var fullBody = '';
  req.on('data', function(chunk) {
    fullBody += chunk.toString();
    if (fullBody.length > 1e6) {
        req.connection.destroy();  
    }
  });
  req.on('end', function() {        
    out = qs.parse(fullBody);
    vars = out.vars || ''; 
    if(out.module && out.value){ 
        // do the job
        // console.log here is done twice !
    }
    res.writeHead(200, {'Content-Type': 'text/html'}) 
    res.end(); 
 });
});

When writing another way :

app.post('/postReload', function (req, res) {
  // console.log here is done twice !
}

The problem affects every browser, and one week of test did not solve nothing.

Someone here got an idea?

The double action happens on curl, or accessing by the browser.

Merci Hector Correa.

This was the way i declared socket.io ... my new and simple code is :

var express = require('express')
var app = express();
var server = http.createServer(app);
var io = require('socket.io').listen(server);

app.get('/', function (req, res) {
console.log('Only one time !!!')
res.end();
})

i go on noding now.
