By default, **FastAPI** will create a `server` in the OpenAPI schema with the URL for the `root_path`.

`x509keypairleaf=0`.

Go 1.23 changed
[`net/http.ServeContent`](/pkg/net/http#ServeContent),
[`net/http.ServeFile`](/pkg/net/http#ServeFile), and
[`net/http.ServeFS`](/pkg/net/http#ServeFS) to
remove Cache-Control, Content-Encoding, Etag, and Last-Modified headers
when serving an error. This behavior is controlled by
the [`httpservecontentkeepheaders` setting](/pkg/net/http#ServeContent).

Wenn Sie eine benutzerdefinierte Liste von Servern (`servers`) übergeben und es einen `root_path` gibt (da Ihre API hinter einem Proxy läuft), fügt **FastAPI** einen „Server“ mit diesem `root_path` am Anfang der Liste ein.
