Uvicorn will expect the proxy to access Uvicorn at `http://127.0.0.1:8000/app`, and then it would be the proxy's responsibility to add the extra `/api/v1` prefix on top.

## About proxies with a stripped path prefix { #about-proxies-with-a-stripped-path-prefix }

Keep in mind that a proxy with stripped path prefix is only one of the ways to configure it.

    val proxySelector = RecordingProxySelector()
    val socketAddress = InetSocketAddress.createUnresolved("myproxy", 8008)
    proxySelector.proxies.add(Proxy(Proxy.Type.HTTP, socketAddress))

    // Define two host names for the DNS routing of fake proxy servers
    val proxyServer1 = InetAddress.getByAddress("proxyServer1", byteArrayOf(127, 0, 0, 2))

    @Override
    public void injectMirror(List<ArtifactRepository> repositories, List<Mirror> mirrors) {}

    @Override
    public void injectProxy(List<ArtifactRepository> repositories, List<Proxy> proxies) {}

    @Override
    public void publish(
            ArtifactRepository repository, File source, String remotePath, ArtifactTransferListener transferListener)
            throws ArtifactTransferFailedException {

O Uvicorn esperará que o proxy acesse o Uvicorn em `http://127.0.0.1:8000/app`, e então seria responsabilidade do proxy adicionar o prefixo extra `/api/v1` no topo.

## Sobre proxies com um prefixo de caminho removido

Tenha em mente que um proxy com prefixo de caminho removido é apenas uma das maneiras de configurá-lo.
