    public void testSetSettingsIndexName() {

For example, you could disable syntax highlighting in Swagger UI.

Without changing the settings, syntax highlighting is enabled by default:

<img src="/img/tutorial/extending-openapi/image02.png">

But you can disable it by setting `syntaxHighlight` to `False`:

{* ../../docs_src/configure_swagger_ui/tutorial001.py hl[3] *}

...and then Swagger UI won't show the syntax highlighting anymore:

<img src="/img/tutorial/extending-openapi/image03.png">

For example:

{* ../../docs_src/conditional_openapi/tutorial001.py hl[6,11] *}

Here we declare the setting `openapi_url` with the same default of `"/openapi.json"`.

And then we use it when creating the `FastAPI` app.

Then you could disable OpenAPI (including the UI docs) by setting the environment variable `OPENAPI_URL` to the empty string, like:

<div class="termy">

```console

		// Test case containing prefix values.
		// Setting prefix to be equal to object name.(Test number 22).
		{bucketNames[0], "minio-object-1.txt", "", "", "", 2, listMultipartResults[9], nil, true},
		// Setting `prefix` to contain the object name as its prefix (Test number 23).
		{bucketNames[0], "min", "", "", "", 2, listMultipartResults[10], nil, true},
		// Setting `prefix` to contain the object name as its prefix (Test number 24).

		}
	}

	// Test for Anonymous/unsigned http request.
	// ListBucketsHandler doesn't support bucket policies, setting the policies shouldn't make any difference.
	anonReq, err := newTestRequest(http.MethodGet, getBucketLocationURL("", bucketName), 0, nil)
	if err != nil {

* **Swagger UI**: served at `/docs`.
    * You can set its URL with the parameter `docs_url`.
    * You can disable it by setting `docs_url=None`.
* **ReDoc**: served at `/redoc`.
    * You can set its URL with the parameter `redoc_url`.
    * You can disable it by setting `redoc_url=None`.

For example, to set Swagger UI to be served at `/documentation` and disable ReDoc:

If the client tries to go to `/items`, by default, it would be redirected to `/items/`.

But before setting the *CLI Option* `--forwarded-allow-ips` it could redirect to `http://localhost:8000/items/`.

But maybe your application is hosted at `https://mysuperapp.com`, and the redirection should be to `https://mysuperapp.com/items/`.

By setting `--proxy-headers` now FastAPI would be able to redirect to the right location. 😎

/// warning

Before setting `convert_underscores` to `False`, bear in mind that some HTTP proxies and servers disallow the usage of headers with underscores.

///

## Duplicate headers { #duplicate-headers }

FastAPI will still be able to override it.

///

Then you can reset your overrides (remove them) by setting `app.dependency_overrides` to be an empty `dict`:

```Python
app.dependency_overrides = {}
```
