Goal
Prevent forms from timing out when submitting them after leaving them on-screen for a considerable amount of time. (Laravel defaults to 120 minutes, but that is configurable and could be different site-by-site.)
Implementation
To achieve this, we are sending a caffeine-drip (a request at regular intervals) to keep the session from timing out.
This is only implemented on pages with a _token field, so all other pages will time-out as normal.
Reasoning
I chose this approach to keep the integrity of site-security, by avoiding the following:
- exposing the CSRF Token on an unsecured endpoint.
- eliminating CSRF Token validation on specific routes, or even altogether.
- removing session-timeout on all pages.
Considerations
Routes
This package adds the routes under genealabs/laravel-caffeine. Please verify that these don't collide with your
existing routes.
Dependencies
- Your project should be running Laravel 5.1.
Installation
- Install Caffeine via composer:
composer require genealabs/laravel-caffeine:~0.2- Add the service provider entry in
config\app.php:
GeneaLabs\LaravelCaffeine\LaravelCaffeineServiceProvider::class,- Register the middleware class in
app/Http/kernel.php:
protected $middleware = [
// other entries above
\GeneaLabs\LaravelCaffeine\Http\Middleware\LaravelCaffeineDripMiddleware::class,
];Usage
That was it! It will apply itself automatically where it finds a form
with a _token field while pages are open in browsers.
