S3TransferManager "no_proxy" support in -PREVIEW

[poconnor-lab49]

It looks like the S3TransferManager from software.amazon.awssdk:s3-transfer-manager automatically picks up proxy configurations.

[DEBUG] [2022-12-15T19:23:05Z] [00007f3145ffb6c0] [http-connection] - HTTP_PROXY environment found
[INFO] [2022-12-15T19:23:05Z] [00007f3145ffb6c0] [http-connection] - (STATIC) Connecting to "127.0.0.1" via proxy "foo.bar.baz"

Is there a way to disable this, whether using environment variables or directly setting the proxy configuration like with the S3Client?

S3Client.builder()
      .httpClientBuilder(ApacheHttpClient.builder()
          .proxyConfiguration(ProxyConfiguration.builder()
              .addNonProxyHost("localhost")
              .build())
        );

Hoping I've just missed some documentation, but I don't see anything like this in 2.18.38-PREVIEW

Thanks!

Hi @poconnor-lab49 thanks for reaching out, proxy is not supported at this moment, tracking in #3262

[poconnor-lab49]

Thanks for the help! I've added a feature/bug request in aws-c-http which is where I think the environment variable detection is happening for proxies: awslabs/aws-c-http#413

If that is not the root cause, please let me know where the appropriate repo is to request the change.
