Node.js cross-origin POST. You should response for OPTIONS request first. Something like this.
if (req.method === 'OPTIONS') {
console.log('!OPTIONS');
var headers = {};
// IE8 does not allow domains to be specified, just the *
// headers["Access-Control-Allow-Origin"] = req.headers.origin;
headers["Access-Control-Allow-Origin"] = "*";
headers["Access-Control-Allow-Methods"] = "POST, GET, PUT, DELETE, OPTIONS";

headers["Access-Control-Max-Age"] = '86400'; // 24 hours

a Mersenne Twister implementation in javascript. Makes up for Math.random() not letting you specify a seed value.
/*
I've wrapped Makoto Matsumoto and Takuji Nishimura's code in a namespace
so it's better encapsulated. Now you can have multiple random number generators
and they won't stomp all over eachother's state.
If you want to use this as a substitute for Math.random(), use the random()
method like so:
var m = new MersenneTwister();
