Cakephp 3 Download Large Files

Question

I have the following problem. My Cakephp 3 application stores some BIG files (200mbs), uploaded via FTP. These files are in a folder outside of my project.

When you click on the download link, it starts to be sent to the user, but the site navigation is frozen, not allowing you to browse between other screens.

// no Controller
public function download($id=null) {
   // ... Acessa o registro para capturar o caminho do arquivocakpehp
   $filePath = '/caminho/do/arquivo.xxx';

   return $this->response
                    ->withHeader('Content-Type', 'application/zip')
                    ->withHeader('Content-Disposition', 'attachment;')
                    ->withHeader('Cache-Control', 'max-age=0')
                    ->withHeader('Cache-Control', 'max-age=1')
                    ->withHeader('Expires', 'Mon, 26 Jul 2500 05:00:00 GMT')
                    ->withHeader('Last-Modified', gmdate('D, d M Y H:i:s') . ' PDT')
                    ->withHeader('Cache-Control', 'cache, must-revalidate')
                    ->withHeader('Pragma', 'public')
                    ->withFile($filePath, ['download' => true]);

}

What am I doing wrong? That was one of the ways I tested.
