`StaticHandler` when `setIncludeHidden(false)` is configured.\n\nIn the current implementation, only files whose final path segment (i.e., the file name) begins with a dot (`.`) are treated as “hidden” and are blocked from being served. However, this logic fails in the following cases:\n\n- **Files under hidden directories**: For example, `/.secret/config.txt` — although `.secret` is a hidden directory, the file `config.txt` itself does not start with a dot, so it gets served.\n- **Real-world impact**: Sensitive files placed in hidden directories like `.git`, `.env`, `.aws` may become publicly accessible.\n\nAs a result, the behavior does not meet the expectations set by the `includeHidden=false` configuration, which should ideally protect all hidden files and directories.
