                A path prefix handled by a proxy that is not seen by the application
                but is seen by external clients, which affects things like Swagger UI.

                Read more about it at the
                [FastAPI docs for Behind a Proxy](https://fastapi.tiangolo.com/advanced/behind-a-proxy/).

                **Example**

                ```python

    String HTTP_PROXY_HOST = "http.proxy.host";

    /** The key of the configuration. e.g. 8080 */
    String HTTP_PROXY_PORT = "http.proxy.port";

    /** The key of the configuration. e.g.  */
    String HTTP_PROXY_USERNAME = "http.proxy.username";

    /** The key of the configuration. e.g.  */
    String HTTP_PROXY_PASSWORD = "http.proxy.password";

  fun proxiedRequestGetsCorrectRequestUrl() {
    server.enqueue(
      MockResponse.Builder()
        .body("Result")
        .build(),
    )
    val proxiedClient =
      OkHttpClient.Builder()
        .proxy(server.toProxyAddress())
        .readTimeout(Duration.ofMillis(100))
        .build()
    val request = Request.Builder().url("http://android.com/").build()
    proxiedClient.newCall(request).execute().use { response ->

	return sha256Sum, releaseTime, releaseInfo, err
}

func getUpdateTransport(timeout time.Duration) http.RoundTripper {
	var updateTransport http.RoundTripper = &http.Transport{
		Proxy:                 http.ProxyFromEnvironment,
		DialContext:           xhttp.NewInternodeDialContext(timeout, globalTCPOptions),
		IdleConnTimeout:       timeout,
		TLSHandshakeTimeout:   timeout,

相対URLを使っているので、APIが`https://example.com/`にある場合、`https://example.com/token`を参照します。しかし、APIが`https://example.com/api/v1/`にある場合は`https://example.com/api/v1/token`を参照することになります。

相対 URL を使うことは、[プロキシと接続](../../advanced/behind-a-proxy.md){.internal-link target=_blank}のような高度なユースケースでもアプリケーションを動作させ続けるために重要です。

///

このパラメーターはエンドポイント/ *path operation*を作成しません。しかし、URL`/token`はクライアントがトークンを取得するために使用するものであると宣言します。この情報は OpenAPI やインタラクティブな API ドキュメントシステムで使われます。
