There are many situations in which you need to notify an error to a client that is using your API.

This client could be a browser with a frontend, a code from someone else, an IoT device, etc.

You could need to tell the client that:

* The client doesn't have enough privileges for that operation.
* The client doesn't have access to that resource.
* The item the client was trying to access doesn't exist.
* etc.

        includeIPv6,
        post,
        resolvePrivateAddresses,
        resolvePublicAddresses,
      )
    }

### CrawlerClientFactory

Pattern-based client selection (from `crawler/client.xml`):
- `http:.*`, `https:.*` → SwitchableHttpClient
- `file:.*` → FileSystemClient
- `smb:.*` → SmbClient (SMB2+), `smb1:.*` → SmbClient (SMB1)
- `ftp:.*`, `ftps:.*` → FtpClient
- `storage:.*` → StorageClient, `s3:.*` → S3Client, `gcs:.*` → GcsClient
