## A: Secure Sessions Howto
Secure sessions are easy, but not very well documented.
Here's a recipe for secure sessions in Node.js when NginX is used as an SSL proxy:

The desired configuration for using NginX as an SSL proxy is to offload SSL processing
and to put a hardened web server in front of your Node.js application, like:

[NODE.JS APP] <- HTTP -> [NginX] <- HTTPS -> [PUBLIC INTERNET] <-> [CLIENT]

Edit for express 4.X and >:  Express no longer uses Connect as its middleware framework, it implements its own now.

## monitor.sh
#!/bin/bash
UP=$(pgrep mysql | wc -l);
if [ "$UP" -ne 1 ];
then
        echo "MySQL is down.";
        sudo service mysql start

else
        echo "All is well.";
fi

## app.js
var express = require('express');

var app   = express();
var app2  = express();

app.use(express.vhost('app1.example.com', require('./app1').app));
app.use(express.vhost('app2.example.com', app2));

app2.get('/', function(req, res) {
  res.send('app 2');

## ngGrid.js
/**
 * Grid directive for angularJS, based on dalcib's Angular Grid https://gist.github.com/2630138
 * It's events are more angular-style and it operates on special object NavigationVector. It allows
 * to select a row and to add custom rows at the bottom (for example to notify, that there are no rows found)
 * When creating NavigationVector object you should pass the scope in which it will be declared in order
 * to properly bind $watch expressions. Thanks to this you will be able to update index, selected or even
 * items properties and other properties will be updated to match the change you made.
 *
 * Example:
 	<table ng-grid="" width="100%">

                                                           NSError *error) {

var querystring = require('querystring');

var original = 'http://example.com/product/abcde.html';

console.log(escaped);
// http%3A%2F%2Fexample.com%2Fproduct%2Fabcde.html

var unescaped = querystring.unescape(escaped);
console.log(unescaped);

## Helper code

var offset = new Date().getTimezoneOffset() * 60 * 1000;
function parseAspNetUTCDateToJSDate(jsonDate) {
    var parsedDate = new Date(parseInt(jsonDate.substr(6)) + offset);
    return parsedDate;
}

Handlebars.registerHelper('date', function (date, block) {
    return parseAspNetUTCDateToJSDate(date).toDateString(); //Return a shortened version of the date
});

## main.js
var http = require('http');
var sys = require('sys');
var exec = require('child_process').exec;
var util = require('util');
var fs = require('fs');

http.createServer(function(request, response) {
	var dummyContent = '<!doctype html><html><head><title>Test</title><meta charset="utf-8"></head><body><p>Hello world!</p></body></html>';
	var htmlFileName = "page.html", pdfFileName = "page.pdf";


## dateFormatter.js
/**
 * Date formatting helper.
 *
 * Date helper takes a SC.DateTime and return a formatted string based on the format
 * parameter. If no format is given, it uses %c as default.
 *
 * @param format a format string
