Laravel 4 lib that provides AJAX redirects in Redirector.

}

• Put php classes in /app/lib/RedirectAxax directory
• Add "app_path().'/lib'" to ClassLoader array in /start/global.php
• Bind alias in /app/config/app.php: 'Redirect'=> 'RedirectAjax\RedirectAjax'

After that redirects called in ajax requests will output JSON:

{"redirect":"http://example.com"} 

with status code 200 (to prevent browser redirecting).

Also jQuery global ajax setup included to resolve this redirects automatically.
