```
class HttpURLConnectionDecorator
extends HttpURLConnection
```
Decorator for a HttpURLConnection that is used for writing data. The default implementation doesn't send a request for small amounts of data until the input stream is opened or the request status is queried. Therfore this decorator returns a custom output stream through getOutputStream() that queries the HTTP status code when the stream is closed. All other operations are simply delegate to the original instances.
