**FastAPI** verwendet diese *vorübergehende* Response, um die Cookies (auch Header und Statuscode) zu extrahieren und fügt diese in die endgültige Response ein, die den von Ihnen zurückgegebenen Wert enthält, gefiltert nach einem beliebigen `response_model`.

Sie können den `Response`-Parameter auch in Abhängigkeiten deklarieren und darin Cookies (und Header) setzen.

Wenn der Client beispielsweise versucht, einen `tool` Query-Parameter mit dem Wert `plumbus` zu senden, wie:

```http
https://example.com/items/?limit=10&tool=plumbus
```

erhält er eine **Error-Response**, die ihm mitteilt, dass der Query-Parameter `tool` nicht erlaubt ist:

```json

## Forbid Extra Query Parameters { #forbid-extra-query-parameters }

In some special use cases (probably not very common), you might want to **restrict** the query parameters that you want to receive.

You can use Pydantic's model configuration to `forbid` any `extra` fields:

	const MaxIntermediateCAs = 10
	var (
		peerCertificates = make([]*x509.Certificate, 0, len(r.TLS.PeerCertificates))
		intermediates    *x509.CertPool
		numIntermediates int
	)
	for _, cert := range r.TLS.PeerCertificates {
		if cert.IsCA {
			numIntermediates++
			if numIntermediates > MaxIntermediateCAs {

Because this code is executed before the application **starts** taking requests, and right after it **finishes** handling requests, it covers the whole application **lifespan** (the word "lifespan" will be important in a second 😉).
