Now the client will get the same *HTTP 500 Internal Server Error* response, but the server will have our custom `InternalError` in the logs. 😎

## Execution of dependencies with `yield` { #execution-of-dependencies-with-yield }

The sequence of execution is more or less like this diagram. Time flows from top to bottom. And each column is one of the parts interacting or executing code.

# Exécuter un serveur manuellement - Uvicorn

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.

# Lifespan Events { #lifespan-events }

You can define logic (code) that should be executed before the application **starts up**. This means that this code will be executed **once**, **before** the application **starts receiving requests**.

The same way, you can define logic (code) that should be executed when the application is **shutting down**. In this case, this code will be executed **once**, **after** having handled possibly **many requests**.
