How to write to the user's cache?

Question

Laravel

in Controller.php I check for the presence of a partner id and if I find it, I cache it, but for some reason it is entered into the site's global cache

public function __construct()
  {
    $this->middleware(function ($request, $next) {
      if($request->has('utm')) Cache::put('partner_id', trim(htmlspecialchars((int)$request->utm)), now()->addYear());
      return $next($request);
    });
  }
