How in Laravel 5.1 will save data to session from Exception Handler?

Question

Sessions

Hey! Please help, can anyone come across, the problem is the following (Laravel 5.1):
I'm trying to change the behavior when throwing TokenMismatchException in this way: in Exceptions/Handler.php:

public function render($request, Exception $e)
    {
        if ($e instanceof TokenMismatchException){
            session()->put('put', 'qwe');
            return redirect()->route('test1')->with('with', 'sad');
        }
        return parent::render($request, $e);
    }

Everything would be fine, but the variables in the session are not saved when moving along the route.
In Laravel 5.2, variables are stored in the session.

So there was a bug in Laravel, it was fixed. Update to 5.2 or see changelog from 5.1 to 5.2 and fork or offer a backport in 5.1.
