## Technical Details { #technical-details }

The class `BackgroundTasks` comes directly from <a href="https://www.starlette.dev/background/" class="external-link" target="_blank">`starlette.background`</a>.

La principale chose dont vous avez besoin pour exécuter une application **FastAPI** sur une machine serveur distante est un programme serveur ASGI tel que **Uvicorn**.

Il existe 3 principales alternatives :

* <a href="https://www.uvicorn.dev/" class="external-link" target="_blank">Uvicorn</a> : un serveur ASGI haute performance.
* <a href="https://hypercorn.readthedocs.io/" class="external-link" target="_blank">Hypercorn</a> : un serveur

No HTTP Basic Auth, a aplicação espera um cabeçalho que contém um usuário e uma senha.

Caso ela não receba, ela retorna um erro HTTP 401 "Unauthorized".

E retorna um cabeçalho `WWW-Authenticate` com o valor `Basic`, e um parâmetro opcional `realm`.

Isso sinaliza ao navegador para mostrar o prompt integrado para um usuário e senha.
