### Post Streaming ([.kt][PostStreamingKotlin], [.java][PostStreamingJava])

Here we `POST` a request body as a stream. The content of this request body is being generated as it's being written. This example streams directly into the [Okio](https://github.com/square/okio) buffered sink. Your programs may prefer an `OutputStream`, which you can get from `BufferedSink.outputStream()`.
