if session is expired redirect user to login in laravel 5.4

caffeine also looks for a meta tag in addition to forms with a _token field. You could add

<meta name="csrf_token" content="{{ csrf_token() }}">

to your master view and caffeine will work on all pages.

Thanks. I think that was happening because I forgot to put the middleware constructor in the controllers... But your solution is also good. Thanks @Cronix

You shouldn't need to add the middleware to controllers, just register the middleware. Basically the middleware looks at the HTML before it gets sent to the browser and checks for the _token or meta tag, and inserts the little ajax javascript snippet for the drip if it finds either of those 2 things on the page. So if the HTML doesn't contain either of those 2 things, then it won't perform the ajax drip request. So really, there isn't a need to add it manually to controllers.
