Swagger UI will handle it behind the scenes for you, but it needs this "redirect" helper.

### Create a *path operation* to test it

Now, to be able to test that everything works, create a *path operation*:

{* ../../docs_src/custom_docs_ui/tutorial001.py hl[36:38] *}

### Test it

# Global Dependencies

For some types of applications you might want to add dependencies to the whole application.

Similar to the way you can [add `dependencies` to the *path operation decorators*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, you can add them to the `FastAPI` application.

In that case, they will be applied to all the *path operations* in the application:

```Python hl_lines="16"

"میان‌افزار" یک تابع است که با هر درخواست(request) قبل از پردازش توسط هر path operation (عملیات مسیر) خاص کار می‌کند. همچنین با هر پاسخ(response) قبل از بازگشت آن نیز کار می‌کند.

* هر **درخواستی (request)** که به برنامه شما می آید را می گیرد.
* سپس می تواند کاری برای آن **درخواست** انجام دهید یا هر کد مورد نیازتان را اجرا کنید.
* سپس **درخواست** را به بخش دیگری از برنامه (توسط یک path operation مشخص) برای پردازش ارسال می کند.

// This function will block till the operation that produces `h` has completed.

- Additionally in the case of the erasure coded setup `tags.objectLocation` provides per object details about
  - Pool number the object operation was performed on.
  - Set number the object operation was performed on.
  - The list of drives participating in this operation belong to the set.
