**FastAPI** will use that *temporal* response to extract the cookies (also headers and status code), and will put them in the final response that contains the value you returned, filtered by any `response_model`.

You can also declare the `Response` parameter in dependencies, and set cookies (and headers) in them.

## Return a `Response` directly { #return-a-response-directly }

### Rewriting Responses

Symmetrically, interceptors can rewrite response headers and transform the response body. This is generally more dangerous than rewriting request headers because it may violate the webserver's expectations!

    client.listener.assertTextMessage(message)
  }

  @Test
  fun messagesCompressedWhenConfigured() {
    val headers = headersOf("Sec-WebSocket-Extensions", "permessage-deflate")
    client.initWebSocket(random, responseHeaders = headers)
    server.initWebSocket(random, responseHeaders = headers)
    val message = repeat('a', RealWebSocket.DEFAULT_MINIMUM_DEFLATE_SIZE.toInt())
    server.webSocket!!.send(message)

	}

	// Since the list of signed headers value contained `expect`, the default value of `100-continue` will be added to extracted signed headers.
	if extractedExpect != expectedExpect {
		t.Errorf("expect header incorrect value: expected `%s`, got `%s`", expectedExpect, extractedExpect)
	}

	// case where the headers don't contain the one of the signed header in the signed headers list.

    return out
  }

  private fun sendHeaderFrames(
    outFinished: Boolean,
    headers: List<Header>,
  ): Buffer {
    val out = Buffer()
    Http2Writer(out, true).headers(outFinished, expectedStreamId, headers)
    return out
  }

  private fun sendPushPromiseFrames(
    streamId: Int,
    headers: List<Header>,
  ): Buffer {
    val out = Buffer()
