Experimental support for server-sent events.
API is not considered stable and may change at any time.

Note que nós estamos utilizando async/await com o novo `AsyncClient` - a requisição é assíncrona.

/// warning | "Aviso"

Se a sua aplicação depende dos eventos de vida útil (*lifespan*), o `AsyncClient` não acionará estes eventos. Para garantir que eles são acionados, utilize o `LifespanManager` do <a href="https://github.com/florimondmanca/asgi-lifespan#usage" class="external-link" target="_blank">florimondmanca/asgi-lifespan</a>.
