Redirect Loop Laravel 5.1 in Fortrabbit

Question

I have deployed a laravel app to fortrabbit. The deployed app is a simple app just to test authentication and middleware ('auth' and 'guest'). I have tried the app in localhost, the authentication and middleware worked fine. When I tried my app in fortrabbit, the authentication worked properly but there was an issue with the middleware. I get

This webpage has a redirect loop, ERR_TOO_MANY_REDIRECTS

every time I log into the home page.

routes.php:

Route::get('/','UserController@getIndex');

Route::group(['middleware' => 'guest'], function() {

   Route::get('login','UserController@getLogin');
   Route::post('login','UserController@postLogin');

   Route::get('register','UserController@getRegister');
   Route::post('register','UserController@postRegister');

});

Route::group(['middleware' => 'auth'], function() {

   Route::get('home','MainController@getHome');
   Route::get('logout','MainController@logout');

});

Authenticate.php for 'auth' middleware:

public function handle($request, Closure $next)
{

    if ($this->auth->guest()) {
        if ($request->ajax()) {
            return response('Unauthorized.', 401);
        } else{
            return redirect()->guest('/login');
    }

    return $next($request);
}

RedirectIfAuthenticated.php for 'guest' middleware:

public function handle($request, Closure $next)
{
    if ($this->auth->check()) {
        return redirect('home');
    }

    return $next($request);
}

Is there any file/setting in fortrabbit that I have to configure to run this app properly?

Answer 1

After modifying config/cache.php with Fortrabbit memcache configuration (link), we should change not only the value of CACHE_DRIVER but also the SESSION_DRIVER to memcached in .env file

Your auth middleware looks off to me.
If guest() do this, if not guest redirect to login. Shouldn't you be redirected to login if you are a guest on a page where guests are not allowed?
You're in an endless loop because once you login, you are no longer a guest, so you get redirected to 'home', which triggers the 'auth' that's off and redirects you to login, which triggers 'guest' which redirects you ...

I think you're auth middleware should look like this, source from Laravel on Github

public function handle($request, Closure $next)
{
    if ($this->auth->guest()) {
        if ($request->ajax()) {
            return response('Unauthorized.', 401);
        } else {
            return redirect()->guest('auth/login');
        }
    }
    return $next($request);
}
