## `TrustedHostMiddleware`

Enforces that all incoming requests have a correctly set `Host` header, in order to guard against HTTP Host Header attacks.

The following arguments are supported:

<div class="wrapper">
    <jsp:include page="/WEB-INF/view/common/admin/header.jsp"></jsp:include>
    <jsp:include page="/WEB-INF/view/common/admin/sidebar.jsp">
        <jsp:param name="menuCategoryType" value="system"/>

OpenAPI define os seguintes esquemas de segurança:

* `apiKey`: uma chave específica de aplicação que pode vir de:
    * Um parâmetro query.
    * Um header.
    * Um cookie.
* `http`: padrão HTTP de sistemas autenticação, incluindo:
    * `bearer`: um header de `Authorization` com valor de `Bearer` adicionado de um token. Isso é herança do OAuth2.
    * HTTP Basic authentication.
    * HTTP Digest, etc.

In diesen Fällen können Sie einen `Response`-Parameter verwenden.

## Einen `Response`-Parameter verwenden

Sie können einen Parameter vom Typ `Response` in Ihrer *Pfadoperation-Funktion* deklarieren (wie Sie es auch für Cookies und Header tun können).

Anschließend können Sie den `status_code` in diesem *vorübergehenden* Response-Objekt festlegen.
