## Crie um `main.py`
Copie o exemplo em um arquivo `main.py`:

```Python
{!../../docs_src/security/tutorial001.py!}
```

## Execute-o

/// info | "informação"



///

	Primeiro, instale <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

	Ex: `pip install python-multipart`.

## Retrying Requests

Sometimes connections fail: either a pooled connection was stale and disconnected, or the webserver itself couldn’t be reached. OkHttp will retry the request with a different route if one is available.

## [Calls](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-call/)

					if !exist {
						dr, _ = configClient.NetworkingV1().DestinationRules(drNamespace).Get(context.Background(), drName, metav1.GetOptions{})
						if dr == nil {
							fmt.Fprintf(writer,
								"WARNING: Proxy is stale; it references to non-existent destination rule %s.%s\n",
								drName, drNamespace)
						}
						recordDestinationRules[newResourceID(drNamespace, drName)] = dr.DeepCopy()
					}
				}
				if dr != nil {

        .header("Cache-Control", "max-stale=180")
        .build()
    val response = client.newCall(request).execute()
    assertThat(response.body.string()).isEqualTo("A")
    assertThat(response.header("Warning")).isEqualTo(
      "110 HttpURLConnection \"Response is stale\"",
    )
  }

  @Test

/*
To clean up stale ztunnels

	we may need to ztunnel to send its (uid, bootid / boot time) to us
	so that we can remove stale entries when the ztunnel pod is deleted
	or when the ztunnel pod is restarted in the same pod (remove old entries when the same uid connects again, but with different boot id?)

    Como esse arquivo **não muda com frequência**, o Docker irá detectá-lo e usar o **cache** para esse passo, habilitando o cache para o próximo passo também.
