public class LazyGzipCompressingOutputStream
extends java.io.FilterOutputStream
```
A filter output stream for an HttpServletResponse's output stream which starts out by writing to a size-limited byte buffer and defers the decision of whether or not to use GZIP compression to the point where the content written to it exceeds the buffer size or the stream is flushed or closed. If the stream is closed before the buffer size is exceeded, the buffer is written to the HttpServletResponse's output stream without compression activated. If the stream is flushed before compression was activated, the buffer content is flushed to the response's output stream, the buffer is released, and compression will not be activated for this stream ever. Flushing the stream after compression has been activated will delegate to the GZIPOutputStream's flush method.
The stream is not thread-safe. Multiple threads trying to write to it concurrently may end up in a race condition, may overwrite buffer content and may cause inconsistencies when crossing the size threshold for compression.
