* as a single request/response exchange.

 * ## Modern TLS
 *
 * There are trade-offs when selecting which options to include when negotiating a secure connection
 * to a remote host. Newer TLS options are quite useful:
 *
 *  * Server Name Indication (SNI) enables one IP address to negotiate secure connections for
 *    multiple domain names.

强制所有传入请求必须是 `https` 或 `wss`。

任何传向 `http` 或 `ws` 的请求都会被重定向至安全方案。

```Python hl_lines="2  6"
{!../../docs_src/advanced_middleware/tutorial001.py!}
```

## `TrustedHostMiddleware`

强制所有传入请求都必须正确设置 `Host` 请求头，以防 HTTP 主机头攻击。

```Python hl_lines="2  6-8"
{!../../docs_src/advanced_middleware/tutorial002.py!}
```
