Laravel middleware does not work when set as global middleware

I have a middleware for setting the locale of my laravel application by getting the value from the session before each and every request.

I have a route that sets this variable,and I apply this middleware to all routes,including this one.

Here is my middleware:

namespace App\Http\Middleware;

use App;
use Closure;
use Session;

class LocaleMiddleware
* Handle an incoming request.
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
public function handle($request, Closure $next)

return $next($request);

and here is my route for setting the language

public function setLang(string $lang)
Session::put('locale', $lang);

return back();

Now here is the problem.If I set that middleware to be global,in the kernel file,it does not take effect.The locale is not set properly.

If I manually apply that middleware to every route,it works.

If I assign that middleware to the
middleware group,in the kernel file, that is automatically applied to all routes,it works as well.

This confuses me a lot.Please share your advice with me! thanks :)

I finally found an answer for that.

The middleware responsible for starting sessions is not a global middleware,it is only in the web middleware group.Therefore,laravel was unable to access the session ,since my middleware was run before they were even started.
