    The summary is that it ignores one file in favor of the other.
    util.concurrent, like nearly all our packages, has two .gwt.xml files: one

    writing it has test supersource but no prod supersource.

Und Ihre **FastAPI**-Anwendung mit WebSockets antwortet:

Sie können viele Nachrichten senden (und empfangen):

<img src="/img/tutorial/websockets/image04.png">

Und alle verwenden dieselbe WebSocket-Verbindung.

## Verwendung von `Depends` und anderen { #using-depends-and-others }

In WebSocket-Endpunkten können Sie Folgendes aus `fastapi` importieren und verwenden:

* `Depends`

	diskFillFraction = 0.99

	// diskReserveFraction is the fraction of a disk where we will fill other server pools first.
	// If all pools reach this, we will use all pools with regular placement.
	diskReserveFraction = 0.15

	// diskAssumeUnknownSize is the size to assume when an unknown size upload is requested.
	diskAssumeUnknownSize = 1 << 30
