There are several custom response classes you can use to create an instance and return them directly from your *path operations*.

Read more about it in the [FastAPI docs for Custom Response - HTML, Stream, File, others](https://fastapi.tiangolo.com/advanced/custom-response/).

You can import them directly from `fastapi.responses`:

```python
from fastapi.responses import (
    FileResponse,
    HTMLResponse,

    private static final Logger logger = LogManager.getLogger(AbstractCrawlerClient.class);

    /** The MIME type for application/octet-stream. */
    protected static final String APPLICATION_OCTET_STREAM = "application/octet-stream";

    /** The property name for access timeout. */
    public static final String ACCESS_TIMEOUT_PROPERTY = "accessTimeout";
