node.js code implementation

I have this code:

var http = require('http')

, url = require('url')

, util = require('util')

, exec = require('child_process').exec;

var site = [url removed, login to view](80, "[url removed, login to view]", false);

var req = [url removed, login to view]("GET", "/");

[url removed, login to view]();

[url removed, login to view]('response', function(res){

if([url removed, login to view] !== 200){

// launch a new instance

var ec2 = require("ec2")

, fs = require("fs");

// Read in the configuration above.

var configuration =

[url removed, login to view]([url removed, login to view]("[url removed, login to view]", "utf8"));

// Create an ec2 function that uses your configuration.

ec2 = ec2(configuration)

// Run an instance and wait for it to become ready.

ec2("RunInstances", {

ImageId: "ami-XXXXXX"

, KeyName: "micros-ie"

, InstanceType: "[url removed, login to view]"

, MinCount: 1

, MaxCount: 1

}, function (error, response) {

if (error) {

throw error

}

ready();

});

} else {

[url removed, login to view]('data', function(chunk){

function puts(error, stdout, stderr) { [url removed, login to view](stdout) }

exec("my command", puts);

});

}

});

basically, i would like to launch a new EC2 instance if the status code is not equal to 200. this works ok, but my problem is that when the code goes into the 'else' loop, i would like to check if the 'site' still returns a 200 status code.

So, i need this to be put into a function and then use recursion.

Also, the output of the exec("my command", puts); needs to be fed into a redis database.
