In this case, you can return the file path directly from your *path operation* function.

## Custom response class

You can create your own custom response class, inheriting from `Response` and using it.

For example, let's say that you want to use <a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a>, but with some custom settings not used in the included `ORJSONResponse` class.

The same as when using a custom CDN, the first step is to disable the automatic docs, as those use the CDN by default.

To disable them, set their URLs to `None` when creating your `FastAPI` app:

```Python hl_lines="9"
{!../../../docs_src/custom_docs_ui/tutorial002.py!}
```

### Include the custom docs for static files

// CHECK: %[[CUSTOM_0:.*]] = "tfl.custom"(%[[CONV2D_0]], %[[CONST_2]]) <{custom_code = "FlexMinimum", custom_option = #tfl<const_bytes : "0x074D696E696D756D001812074D696E696D756D1A001A002A070A01541202300132000002231B1414042801">}> : (tensor<1x3x4x2xf32>, tensor<2xf32>) -> tensor<1x3x4x2xf32>
