/// tip

Notice that here as we are using standard `open()` that doesn't support `async` and `await`, we declare the path operation with normal `def`.

### `FileResponse`

Asynchronously streams a file as the response.

Takes a different set of arguments to instantiate than the other response types:

* `path` - The file path to the file to stream.

		// whether to replicate as the target could be temporarily down
		opts.TargetArn = tgtArn
		replicate := cfg.Replicate(opts)
		var synchronous bool
		if tgt != nil {
			synchronous = tgt.replicateSync
		}
		dsc.Set(newReplicateTargetDecision(tgtArn, replicate, synchronous))
	}
	return dsc
}

// Standard headers that needs to be extracted from User metadata.
var standardHeaders = []string{

enabled by default on listerners. Using multipathtcp="0" reverts to the
pre-Go 1.24 behavior.

### Go 1.23

Go 1.23 changed the channels created by package time to be unbuffered
(synchronous), which makes correct use of the [`Timer.Stop`](/pkg/time/#Timer.Stop)
and [`Timer.Reset`](/pkg/time/#Timer.Reset) method results much easier.
The [`asynctimerchan` setting](/pkg/time/#NewTimer) disables this change.

### <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a>

Starlette est un framework/toolkit léger <abbr title="Le nouveau standard pour construire des applications web asynchrones en Python">ASGI</abbr>, qui est idéal pour construire des services asyncio performants.

Il est très simple et intuitif. Il est conçu pour être facilement extensible et avoir des composants modulaires.

Il offre :
