    Conscrypt is the bundled security provider on Android so it is not necessary
    to configure it on that platform.

    Previously several ASCII punctuation characters were not percent-escaped
    when used with this method. This does not impact already-encoded query

### Checking the current `root_path` { #checking-the-current-root-path }

You can get the current `root_path` used by your application for each request, it is part of the `scope` dictionary (that's part of the ASGI spec).

Here we are including it in the message just for demonstration purposes.

{* ../../docs_src/behind_a_proxy/tutorial001.py hl[8] *}

Then, if you start Uvicorn with:

</div>

Hypercorn 也支持 `--root-path `选项。

/// note | 技术细节

ASGI 规范定义的 `root_path` 就是为了这种用例。

并且 `--root-path` 命令行选项支持 `root_path`。

///

### 查看当前的 `root_path`

获取应用为每个请求使用的当前 `root_path`，这是 `scope` 字典的内容（也是 ASGI 规范的内容）。

我们在这里的信息里包含 `roo_path` 只是为了演示。

{* ../../docs_src/behind_a_proxy/tutorial001.py hl[8] *}

然后，用以下命令启动 Uvicorn：

<div class="termy">

```console
