| Application Routes
|--------------------------------------------------------------------------
|
| Simply tell Laravel the HTTP verbs and URIs it should respond to. It is a
| breeze to setup your application using Laravel's RESTful routing and it
| is perfectly suited for building large applications and simple APIs.
|
| Let's respond to a simple GET request to http://example.com/hello:
|
|		Route::get('hello', function()
|		{
|			return 'Hello World!';
|		});
|
| You can even respond to more than one URI:
|
|		Route::post(array('hello', 'world'), function()
|		{
|			return 'Hello World!';
|		});
|
| It's easy to allow URI wildcards using (:num) or (:any):
|
|		Route::put('hello/(:any)', function($name)
|		{
|			return "Welcome, $name.";
|		});
|

// SHOW Home page

{
	return View::make('home.index');
});

{
	// If you had a database you could easily fetch the content from the database here...

| Application 404 & 500 Error Handlers
|--------------------------------------------------------------------------
|
| To centralize and simplify 404 handling, Laravel uses an awesome event
| system to retrieve the response. Feel free to modify this function to
| your tastes and the needs of your application.
|
| Similarly, we use an event to handle the display of 500 level errors
| within the application. These errors are fired when there is an
| uncaught exception thrown in the application.
|
*/

{
	return Response::error('404');
});

Event::listen('500', function()
{
	return Response::error('500');

| Route Filters
|--------------------------------------------------------------------------
|
| Filters provide a convenient method for attaching functionality to your
| routes. The built-in before and after filters are called before and
| after every request to your application, and you may even create
| other filters that can be attached to individual routes.
|
| Let's walk through an example...
|
| First, define a filter:
|
|		Route::filter('filter', function()
|		{
|			return 'Filtered!';
|		});
|
| Next, attach the filter to a route:
|
|		Router::register('GET /', array('before' => 'filter', function()
|		{
|			return 'Hello World!';
|		}));
|
*/

Route::filter('before', function()
{
	// Do stuff before every request to your application...
});

Route::filter('after', function($response)
{
	// Do stuff after every request to your application...
});

Route::filter('csrf', function()
{
	if (Request::forged()) return Response::error('500');
});

Route::filter('auth', function()
{
	if (Auth::guest()){

		// this code ensures that even when the request is AJAX, the user will be redirected to the login page. Neat!
		if (Request::ajax()) {
			$data = array(
					"location" => '../login'
				);

			return Response::json($data);
		}

		return Redirect::to('login');
	}
});
