## `TrustedHostMiddleware` { #trustedhostmiddleware }

Impose que toutes les requêtes entrantes aient un en-tête `Host` correctement défini, afin de se prémunir contre les attaques de type HTTP Host Header.

`Response` döndürürseniz (veya `JSONResponse` gibi herhangi bir alt sınıfını), veri otomatik olarak dönüştürülmez (bir `response_model` tanımlamış olsanız bile) ve dokümantasyon da otomatik üretilmez (örneğin, üretilen OpenAPI’nin parçası olarak HTTP header `Content-Type` içindeki ilgili "media type" dahil edilmez).

Bununla birlikte, *path operation decorator* içinde `response_class` parametresini kullanarak hangi `Response`’un (örn. herhangi bir `Response` alt sınıfı) kullanılacağını da ilan...

### Set legal hold on an object

PutObject API allows setting legal hold using `x-amz-object-lock-legal-hold` header.

```sh
aws s3api put-object --bucket testbucket --key legalhold --object-lock-legal-hold-status ON --body /etc/issue
```

        // Set structure size to 9 (valid)
        SMBUtil.writeInt2(9, buffer, bufferIndex);
        // Set buffer offset (relative to header start)
        SMBUtil.writeInt2(50, buffer, bufferIndex + 2);
        // Set buffer length
        SMBUtil.writeInt4(8, buffer, bufferIndex + 4);

        // Mock getHeaderStart
        response = spy(response);
