In diesem Abschnitt werden wir sehen, wie man andere Middlewares verwendet.

## ASGI-Middleware hinzufügen { #adding-asgi-middlewares }

Da **FastAPI** auf Starlette basiert und die <abbr title="Asynchrones Server-Gateway-Interface">ASGI</abbr>-Spezifikation implementiert, können Sie jede ASGI-Middleware verwenden.

/// warning | Achtung

Bevor Sie `convert_underscores` auf `False` setzen, bedenken Sie, dass manche HTTP-Proxys und Server die Verwendung von Headern mit Unterstrichen nicht erlauben.

///

## Doppelte Header { #duplicate-headers }

Es ist möglich, doppelte Header zu empfangen. Damit ist gemeint, denselben Header mit mehreren Werten.

{* ../../docs_src/dependencies/tutorial008c_an_py310.py hl[15:16] *}

Bu durumda client, biz `HTTPException` veya benzeri bir şey fırlatmadığımız için olması gerektiği gibi *HTTP 500 Internal Server Error* response'u görür; ancak server **hiç log üretmez** ve hatanın ne olduğuna dair başka bir işaret de olmaz. 😱
