## 단계

브라우저 내 `http://localhost:8080`에서 동작하는 프론트엔드가 있고, 자바스크립트는 `http://localhost`를 통해 백엔드와 통신한다고 가정해봅시다(포트를 명시하지 않는 경우, 브라우저는 `80` 을 기본 포트로 간주합니다).

그러면 브라우저는 백엔드에 HTTP `OPTIONS` 요청을 보내고, 백엔드에서 이 다른 출처(`http://localhost:8080`)와의 통신을 허가하는 적절한 헤더를 보내면, 브라우저는 프론트엔드의 자바스크립트가 백엔드에 요청을 보낼 수 있도록 합니다.

이를 위해, 백엔드는 "허용된 출처(allowed origins)" 목록을 가지고 있어야만 합니다.

metadata                                                                                                                                                                       100%  226    16.6KB/s   00:00
sftp>
```

## Advanced options

### Change default FTP port

Default port '8021' can be changed via

```
--ftp="address=:3021"
```

### Change FTP passive port range

        getMultiset().setCount(e0(), 1, 5));
    expectContents(nCopies(3, e0()));
  }

  /*
   * TODO: test that unmodifiable multisets either throw UOE or return false
   * when both are valid options. Currently we test the UOE cases and the
   * return-false cases but not their intersection
   */

	ErrorHandler func(http.ResponseWriter, *http.Request, error)

	// internal variables
	rewriter *headerRewriter
}

// NewForwarder creates an instance of Forwarder based on the provided list of configuration options
func NewForwarder(f *Forwarder) *Forwarder {
	f.rewriter = &headerRewriter{}
	if f.RoundTripper == nil {
		f.RoundTripper = http.DefaultTransport
	}

	return f
}

type bufPool struct {
	sz   int

But for this example, we'll use a very simple HTML document with some JavaScript, all inside a long string.

This, of course, is not optimal and you wouldn't use it for production.

In production you would have one of the options above.

But it's the simplest way to focus on the server-side of WebSockets and have a working example:

```Python hl_lines="2  6-38  41-43"
{!../../docs_src/websockets/tutorial001.py!}
```

```

### Configure MinIO

```
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio123
minio server /mnt/export
```

Here are all the available options to configure OpenID connect

```
mc admin config set myminio/ identity_openid

KEY:
identity_openid  enable OpenID SSO support

ARGS:

	o.Lifecycle = lc
	o.Versioning = vc
	o.Replication = replicationConfig{
		Config:  replCfg,
		remotes: tgts,
	}
	o.Retention = rcfg
}

// newMetacache constructs a new metacache from the options.
func (o listPathOptions) newMetacache() metacache {
	return metacache{
		id:          o.ID,
		bucket:      o.Bucket,
		root:        o.BaseDir,
		recursive:   o.Recursive,
		status:      scanStateStarted,
