```Python
async with lifespan(app):
    await do_stuff()
```

Cuando creas un context manager o un async context manager como arriba, lo que hace es que, antes de entrar al bloque `with`, ejecutará el código antes del `yield`, y al salir del bloque `with`, ejecutará el código después del `yield`.

En nuestro ejemplo de código arriba, no lo usamos directamente, pero se lo pasamos a FastAPI para que lo use.

İşte o geçmişin bir kısmı.

### Detalles Técnicos: `root_path`

Cuando montas una sub-aplicación como se describe arriba, FastAPI se encargará de comunicar el path de montaje para la sub-aplicación usando un mecanismo de la especificación ASGI llamado `root_path`.

				<li class="page-item"><la:link styleClass="page-link" aria-label="Previous"
						href="/search/prev?q=${f:u(q)}&pn=${f:u(currentPageNumber)}&num=${f:u(pageSize)}&sdh=${f:u(fe:sdh(sdh))}${fe:pagingQuery(null)}${fe:facetQuery()}${fe:geoQuery()}">
						<span aria-hidden="true">&laquo;</span>
						<span class="visually-hidden"><la:message key="labels.prev_page" /></span>
