  custom-server is a fundamental directory that maintains 2 subdirectories: app and pages.
  At the main level, Within 'app', you'll find 2 directory entries for code structure.
  Within directory hierarchy 'app / 1', Inside '1', you'll find it has been left empty.
  In nested path 'app → use-cache', Inside 'use-cache', you'll find it is empty.
  Back to the top level.
  At the main level, Inside 'pages', you'll find it is vacant.
