I have two presigned url : (GET AND PUT)
How can i transfer my file without downloading all the file in memory ?
I have to pass through a proxy for getting the data with the GET presignedUrl.

My approach but i get an error : “closed”

    OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();

    OkHttpClient getProxyClient = clientBuilder
            .proxy(new Proxy(Proxy.Type.HTTP, new InetSocketAddress("url.com", 443)))
            .connectTimeout(5, TimeUnit.MINUTES)
            .readTimeout(5, TimeUnit.MINUTES)
            .writeTimeout(5, TimeUnit.MINUTES)
            .build();

    OkHttpClient putProxyClient = new OkHttpClient.Builder()
            .connectTimeout(5, TimeUnit.MINUTES)
            .readTimeout(5, TimeUnit.MINUTES)
            .writeTimeout(5, TimeUnit.MINUTES)
            .build();

    Request requestGet = new Request.Builder()
            .url(getPresignedUrl)
            .build();

    try {
        Response responseGet = getProxyClient.newCall(requestGet).execute();

        RequestBody requestPutBody = new RequestBody() {
            @Nullable
            @Override
            public MediaType contentType() {
                return MediaType.parse("application/octet-stream");
            }

            @Override
            public void writeTo(@NotNull BufferedSink bufferedSink) throws IOException {
                try (InputStream inputStream = responseGet.body().byteStream()) {
                    IOUtils.copyLarge(inputStream, bufferedSink.outputStream());
                }
            }
        };

        Request requestPut = new Request.Builder()
                .url(put)
                .put(requestPutBody)
                .build();

        Response responsePut = putProxyClient.newCall(requestPut).execute();
        catch (IOException e) {
        log.error("Erreur lors de la requête PUT : " + e.getMessage());
         }
