# Response Headers

## Use a `Response` parameter

You can declare a parameter of type `Response` in your *path operation function* (as you can do for cookies).

And then you can set headers in that *temporal* response object.

```Python hl_lines="1  7-8"
{!../../docs_src/response_headers/tutorial002.py!}
```

And then you can return any object you need, as you normally would (a `dict`, a database model, etc).

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
          val parameters = sslSocket.sslParameters
          val sni = parameters.serverNames
          Log.d("CustomSSLSocketFactory", "old SNI: $sni")
          parameters.serverNames = mutableListOf<SNIServerName>(SNIHostName("cloudflare-dns.com"))
          sslSocket.sslParameters = parameters
        }

        return sslSocket
      }
    }

    client =

            "/users/": {
                "get": {
                    "tags": ["users"],
                    "summary": "Read Users",
                    "operationId": "read_users_users__get",
                    "parameters": [
                        {
                            "required": True,
                            "schema": {"title": "Token", "type": "string"},
                            "name": "token",

* Importieren Sie `HTMLResponse`.
* Übergeben Sie `HTMLResponse` als den Parameter `response_class` Ihres *Pfadoperation-Dekorators*.

```Python hl_lines="2  7"
{!../../docs_src/custom_response/tutorial002.py!}
```

/// info

Der Parameter `response_class` wird auch verwendet, um den „Medientyp“ der Response zu definieren.
